Each Power MOS has an Rdson =0.3ohm (typical value @ 25°C), with intrinsic fast freewheeling diode. Cross conduction protection is achieved using a dead time (td = 1µs typical) be-tween the switch off and switch on of two Power MOS in one leg of a bridge.Using N Channel Power MOS for the upper transis-tors in the bridge requires a gate drive voltage above the power supply voltage. The Bootstrapped (VBOOT) supply is obtained through an internal Os-cillator and few external components to realize a charge pump circuit as shown in Figure 3. The oscil-lator output (VCP) is a square wave at 600kHz (typi-cal) with 10V amplitude. Recommended values/part numbers for the charge pump circuit are shown in Table1.Table 1. Charge Pump External ComponentsValuesLOGIC INPUTSPins IN1A , IN2B , IN1B and IN2B are TTL/CMOS and uC compatible logic inputs. The internal structure is shown in Fig. 4. Typical value for turn-on and turn-off thresholds are respectively Vthon = 1.8V and Vthoff = 1.3V.Pins EN A and EN B have identical input structure with the exception that the drains of the Overcurrent andthermal protection MOSFETs (one for the Bridge A and one for the Bridge B) are also connected to these pins. Due to these connections some care needs to be taken in driving these pins. The EN A and EN B in-puts may be driven in one of two configurations as shown in figures 5 or 6. If driven by an open drain (collector) structure, a pull-up resistor R EN and a ca-pacitor C EN are connected as shown in Fig. 5. If the driver is a standard Push-Pull structure the resistor R EN and the capacitor C EN are connected as shown in Fig. 6. The resistor R EN should be chosen in the range from 2.2k Ω to 180K Ω. Recommended values for R EN and C EN are respectively 100K Ω and 5.6nF.More information on selecting the values is found in the Overcurrent Protection section.Figure 5.

The current control circuit senses the bridge current by sensing the voltage drop across an external sense resistor connected be-tween the source of the two lower power MOS transistors and ground, as shown in Figure 7. As the current in the load builds up the voltage across the sense resistor increases proportionally. When the voltage drop across the sense resistor becomes greater than the voltage at the reference input (VREF A or VREF B ) the sense com-parator triggers the monostable switching the low-side MOS off. The low-side MOS remain off for the time set by the monostable and the motor current recirculates in the upper path. When the monostable times out the bridge will again turn on. Since the internal dead time, used to prevent cross conduction in the bridge, delays the turn on of the power MOS, the effective off time is the sum of the monostable time plus the dead time.Figure 8 shows the typical operating waveforms of the output current, the voltage drop across the sensing re-sistor, the RC pin voltage and the status of the bridge. Immediately after the low-side Power MOS turns on, a high peak current flows through the sensing resistor due to the reverse recovery of the freewheeling diodes. The L6207 provides a 1µs Blanking Time t BLANK that inhibits the comparator output so that this current spike cannot prematurely re-trigger the monostable.INPUTSOUTPUTSDescription (*)EN IN1IN2OUT1OUT2L X X High Z High Z DisableH L L GND GND Brake Mode (Lower Path)H H L Vs GND (Vs)Forward H L H GND (Vs)Vs ReverseHHHVsVsBrake Mode (Upper Path)L620710/23Figure 9 shows the magnitude of the Off Time t OFF versus C OFF and R OFF values. It can be approximately cal-culated from the equations:t RCFALL = 0.6 · R OFF · C OFFt OFF = t RCFALL + t DT = 0.6 · R OFF · C OFF + t DTwhere R OFF and C OFF are the external component values and t DT is the internally generated Dead Time with:20K Ω ≤ R OFF ≤ 100K Ω0.47nF ≤ C OFF ≤ 100nF t DT = 1µs (typical value)Therefore:t OFF(MIN) = 6.6µs t OFF(MAX) = 6msThese values allow a sufficient range of t OFF to implement the drive circuit for most motors.The capacitor value chosen for C OFF also affects the Rise Time t RCRISE of the voltage at the pin RCOFF. The Rise Time t RCRISE will only be an issue if the capacitor is not completely charged before the next time the monostable is triggered. Therefore, the on time t ON , which depends by motors and supply parameters, has to11/23be bigger than t RCRISE for allowing a good current regulation by the PWM stage. Furthermore, the on time t ON can not be smaller than the minimum on time t ON(MIN).t RCRISE = 600 · C OFFFigure 10 shows the lower limit for the on time t ON for having a good PWM current regulation capacity. It has to be said that t ON is always bigger than t ON(MIN) because the device imposes this condition, but it can be smaller than t RCRISE - t DT . In this last case the device continues to work but the off time t OFF is not more constant.So, small C OFF value gives more flexibility for the applications (allows smaller on time and, therefore, higher switching frequency), but, the smaller is the value for C OFF , the more influential will be the noises on the circuit performance.t ON t ON MIN ()> 1.5µs (typ. value)=t ON t RCRISE t DT–>SLOW DECAY MODEFigure 11 shows the operation of the bridge in the Slow Decay mode. At the start of the off time, the lower power MOS is switched off and the current recirculates around the upper half of the bridge. Since the voltage across the coil is low, the current decays slowly. After the dead time the upper power MOS is operated in the synchro-nous rectification mode. When the monostable times out, the lower power MOS is turned on again after some delay set by the dead time to prevent cross conduction.12/23NON-DISSIPATIVE OVERCURRENT PROTECTIONThe L6207 integrates an Overcurrent Detection Circuit (OCD). This circuit provides protection against a short circuit to ground or between two phases of the bridge. With this internal over current detection, the external cur-rent sense resistor normally used and its associated power dissipation are eliminated. Figure 12 shows a sim-plified schematic of the overcurrent detection circuit.To implement the over current detection, a sensing element that delivers a small but precise fraction of the out-put current is implemented with each high side power MOS. Since this current is a small fraction of the output current there is very little additional power dissipation. This current is compared with an internal reference cur-rent I REF. When the output current in one bridge reaches the detection threshold (typically 5.6A) the relative OCD comparator signals a fault condition. When a fault condition is detected, the EN pin is pulled below the turn off threshold (1.3V typical) by an internal open drain MOS with a pull down capability of 4mA. By using an ex-ternal R-C on the EN pin, the off time before recovering normal operation can be easily programmed by means of the accurate thresholds of the logic inputs.Figure 13 shows the Overcurrent Detection operation. The Disable Time t DISABLE before recovering normal oper-ation can be easily programmed by means of the accurate thresholds of the logic inputs. It is affected whether by C EN and R EN values and its magnitude is reported in Figure 14. The Delay Time t DELAY before turning off the bridge when an overcurrent has been detected depends only by C EN value. Its magnitude is reported in Figure 15.C EN is also used for providing immunity to pin EN against fast transient noises. Therefore the value of C EN should be chosen as big as possible according to the maximum tolerable Delay Time and the R EN value should be chosen according to the desired Disable Time.The resistor R EN should be chosen in the range from 2.2KΩ to 180KΩ. Recommended values for R EN and C EN are respectively 100KΩ and 5.6nF that allow obtaining 200µs Disable Time.13/2314/23THERMAL PROTECTIONIn addition to the Ovecurrent Protection, the L6207 integrates a Thermal Protection for preventing the device destruction in case of junction over temperature. It works sensing the die temperature by means of a sensible element integrated in the die. The device switch-off when the junction temperature reaches 165°C (typ. value) with 15°C hysteresis (typ. value).15/23APPLICATION INFORMATIONA typical application using L6207 is shown in Fig. 16. Typical component values for the application are shown in Table 3. A high quality ceramic capacitor in the range of 100 to 200 nF should be placed between the power pins (VS A and VS B) and ground near the L6207 to improve the high frequency filtering on the power supply and reduce high frequency transients generated by the switching. The capacitors connected from the EN A and ENB inputs to ground set the shut down time for the BrgidgeA and BridgeB respectively when an over current is de-tected (see Overcurrent Protection). The two current sensing inputs (SENSE A and SENSE B) should be connect-ed to the sensing resistors with a trace length as short as possible in the layout. The sense resistors should be non-inductive resistors to minimize the di/dt transients across the resistor. To increase noise immunity, unused logic pins (except EN A and EN B) are best connected to 5V (High Logic Level) or GND (Low Logic Level) (see pin description).

For a given output current and driving type the power dissipated by the IC can be easily evaluated, in order to establish which package should be used and how large must be the on-board copper dissipating area to guar-antee a safe operating junction temperature (125°C maximum).THERMAL MANAGEMENTIn most applications the power dissipation in the IC is the main factor that sets the maximum current that can be de-livered by the device in a safe operating condition. Therefore, it has to be taken into account very carefully. Besides the available space on the PCB, the right package should be chosen considering the power dissipation. Heat sinking can be achieved using copper on the PCB with proper area and thickness. Figures 20, 21 and 22 show the Junction-to-Ambient Thermal Resistance values for the PowerSO36, PowerDIP24 and SO24 packages.For instance, using a PowerSO package with copper slug soldered on a 1.5 mm copper thickness FR4 board with 6cm2 dissipating footprint (copper thickness of 35µm), the R th j-amb is about 35°C/W. Fig. 19 shows mount-ing methods for this package. Using a multi-layer board with vias to a ground plane, thermal impedance can be reduced down to 15°C/W.17/2318/23Figure 23.

System Overview3.1 IntroductionThe EFR32 product family combines an energy-friendly MCU with a high performance radio transceiver. The devices are well suited for secure connected IoT multi-protocol devices requiring high performance and low energy consumption. This section gives a short intro-duction to the full radio and MCU system. The detailed functional description can be found in the EFR32xG22 Reference Manual.A block diagram of the EFR32FG22 family is shown in Figure 3.1 Detailed EFR32FG22 Block Diagram on page 7. The diagram shows a superset of features available on the family, which vary by OPN. For more information about specific device features, consult Ordering Information .RESETnPDnPCnPBnPAnRF2G4_IODVDDVREGVDD VREGSW AVDD PAVDD RFVDD DECOUPLEIOVDD Figure 3.1. Detailed EFR32FG22 Block Diagram3.2 RadioThe Wireless Gecko family features a radio transceiver supporting proprietary wireless protocols.3.2.1 Antenna InterfaceThe 2.4 GHz antenna interface consists of a single-ended pin (RF2G4_IO). The external components for the antenna interface in typi-cal applications are shown in the RF Matching Networks section.Rev. 1.2 | 73.2.2 Fractional-N Frequency SynthesizerThe EFR32FG22 contains a high performance, low phase noise, fully integrated fractional-N frequency synthesizer. The synthesizer is used in receive mode to generate the LO frequency for the down-conversion mixer. It is also used in transmit mode to directly generate the modulated RF carrier.The fractional-N architecture provides excellent phase noise performance, frequency resolution better than 100 Hz, and low energy consumption. The synthesizer’s fast frequency settling allows for very short receiver and transmitter wake up times to reduce system energy consumption.3.2.3 Receiver ArchitectureThe EFR32FG22 uses a low-IF receiver architecture, consisting of a Low-Noise Amplifier (LNA) followed by an I/Q down-conversion mixer. The I/Q signals are further filtered and amplified before being sampled by the IF analog-to-digital converter (IFADC).The IF frequency is configurable from 150 kHz to 1371 kHz. The IF can further be configured for high-side or low-side injection, provid-ing flexibility with respect to known interferers at the image frequency.The Automatic Gain Control (AGC) module adjusts the receiver gain to optimize performance and avoid saturation for excellent selec-tivity and blocking performance. The 2.4 GHz radio is calibrated at production to improve image rejection performance.Demodulation is performed in the digital domain. The demodulator performs configurable decimation and channel filtering to allow re-ceive bandwidths ranging from 0.1 to 2530 kHz. High carrier frequency and baud rate offsets are tolerated by active estimation and compensation. Advanced features supporting high quality communication under adverse conditions include forward error correction by block and convolutional coding as well as Direct Sequence Spread Spectrum (DSSS).A Received Signal Strength Indicator (RSSI) is available for signal quality metrics, for level-based proximity detection, and for RF chan-nel access by Collision Avoidance (CA) or Listen Before Talk (LBT) algorithms. An RSSI capture value is associated with each received frame and the dynamic RSSI measurement can be monitored throughout reception.3.2.4 Transmitter ArchitectureThe EFR32FG22 uses a direct-conversion transmitter architecture. For constant envelope modulation formats, the modulator controls phase and frequency modulation in the frequency synthesizer. Transmit symbols or chips are optionally shaped by a digital shaping filter. The shaping filter is fully configurable, including the BT product, and can be used to implement Gaussian or Raised Cosine shap-ing.Carrier Sense Multiple Access - Collision Avoidance (CSMA-CA) or Listen Before Talk (LBT) algorithms can be automatically timed by the EFR32FG22. These algorithms are typically defined by regulatory standards to improve inter-operability in a given bandwidth be-tween devices that otherwise lack synchronized RF channel access.3.2.5 Packet and State TraceThe EFR32FG22 Frame Controller has a packet and state trace unit that provides valuable information during the development phase. It features:•Non-intrusive trace of transmit data, receive data and state information•Data observability on a single-pin UART data output, or on a two-pin SPI data output•Configurable data output bitrate / baudrate•Multiplexed transmitted data, received data and state / meta information in a single serial data stream3.2.6 Data BufferingThe EFR32FG22 features an advanced Radio Buffer Controller (BUFC) capable of handling up to 4 buffers of adjustable size from 64 bytes to 4096 bytes. Each buffer can be used for RX, TX or both. The buffer data is located in RAM, enabling zero-copy operations.3.2.7 Radio Controller (RAC)The Radio Controller controls the top level state of the radio subsystem in the EFR32FG22. It performs the following tasks:•Precisely-timed control of enabling and disabling of the receiver and transmitter circuitry•Run-time calibration of receiver, transmitter and frequency synthesizer•Detailed frame transmission timing, including optional LBT or CSMA-CA3.2.8 RFSENSE InterfaceThe RFSENSE block allows the device to remain in EM2, EM3 or EM4 and wake when RF energy above a specified threshold is detec-ted. When operated in selective mode, the RFSENSE block performs OOK preamble and sync word detection, preventing false wake-up events.3.3 General Purpose Input/Output (GPIO)EFR32FG22 has up to 26 General Purpose Input/Output pins. Each GPIO pin can be individually configured as either an output or in-put. More advanced configurations including open-drain, open-source, and glitch-filtering can be configured for each individual GPIO pin. The GPIO pins can be overridden by peripheral connections, like SPI communication. Each peripheral connection can be routed to several GPIO pins on the device. The input value of a GPIO pin can be routed through the Peripheral Reflex System to other peripher-als. The GPIO subsystem supports asynchronous external pin interrupts.All of the pins on ports A and port B are EM2 capable. These pins may be used by Low-Energy peripherals in EM2/3 and may also be used as EM2/3 pin wake-ups. Pins on ports C and D are latched/retained in their current state when entering EM2 until EM2 exit upon which internal peripherals could once again drive those pads.A few GPIOs also have EM4 wake functionality. These pins are listed in the Alternate Function Table.3.4 Clocking3.4.1 Clock Management Unit (CMU)The Clock Management Unit controls oscillators and clocks in the EFR32FG22. Individual enabling and disabling of clocks to all periph-eral modules is performed by the CMU. The CMU also controls enabling and configuration of the oscillators. A high degree of flexibility allows software to optimize energy consumption in any specific application by minimizing power dissipation in unused peripherals and oscillators.3.4.2 Internal and External OscillatorsThe EFR32FG22 supports two crystal oscillators and fully integrates four RC oscillators, listed below.• A high frequency crystal oscillator (HFXO) with integrated load capacitors, tunable in small steps, provides a precise timing refer-ence for the MCU. The HFXO provides excellent RF clocking performance using a 38.4 MHz crystal. The HFXO can also support an external clock source such as a TCXO for applications that require an extremely accurate clock frequency over temperature.• A 32.768 kHz crystal oscillator (LFXO) provides an accurate timing reference for low energy modes.•An integrated high frequency RC oscillator (HFRCO) is available for the MCU system, when crystal accuracy is not required. The HFRCO employs fast start-up at minimal energy consumption combined with a wide frequency range, from 1 MHz to 38.4 MHz.•An integrated fast start-up RC oscillator (FSRCO) that runs at a fixed 20 MHz•An integrated low frequency 32.768 kHz RC oscillator (LFRCO) for low power operation where high accuracy is not required.•An integrated ultra-low frequency 1 kHz RC oscillator (ULFRCO) is available to provide a timing reference at the lowest energy con-sumption in low energy modes.3.5 Counters/Timers and PWM3.5.1 Timer/Counter (TIMER)TIMER peripherals keep track of timing, count events, generate PWM outputs and trigger timed actions in other peripherals through the Peripheral Reflex System (PRS). The core of each TIMER is a 16-bit or 32-bit counter with up to 3 compare/capture channels. Each channel is configurable in one of three modes. In capture mode, the counter state is stored in a buffer at a selected input event. In compare mode, the channel output reflects the comparison of the counter to a programmed threshold value. In PWM mode, the TIMER supports generation of pulse-width modulation (PWM) outputs of arbitrary waveforms defined by the sequence of values written to the compare registers. In addition some timers offer dead-time insertion.See 3.13 Configuration Summary for information on the feature set of each timer.3.5.2 Low Energy Timer (LETIMER)The unique LETIMER is a 24-bit timer that is available in energy mode EM0 Active, EM1 Sleep, EM2 Deep Sleep, and EM3 Stop. This allows it to be used for timing and output generation when most of the device is powered down, allowing simple tasks to be performed while the power consumption of the system is kept at an absolute minimum. The LETIMER can be used to output a variety of wave-forms with minimal software intervention. The LETIMER is connected to the Peripheral Reflex System (PRS), and can be configured to start counting on compare matches from other peripherals such as the Real Time Clock.3.5.3 Real Time Clock with Capture (RTCC)The Real Time Clock with Capture (RTCC) is a 32-bit counter providing timekeeping down to EM3. The RTCC can be clocked by any of the on-board low-frequency oscillators, and it is capable of providing system wake-up at user defined intervals.A secondary RTC is used by the RF protocol stack for event scheduling, leaving the primary RTCC block available exclusively for appli-cation software.3.5.4 Back-Up Real Time Counter (BURTC)The Back-Up Real Time Counter (BURTC) is a 32-bit counter providing timekeeping in all energy modes, including EM4. The BURTC can be clocked by any of the on-board low-frequency oscillators, and it is capable of providing system wake-up at user-defined inter-vals.3.5.5 Watchdog Timer (WDOG)The watchdog timer can act both as an independent watchdog or as a watchdog synchronous with the CPU clock. It has windowed monitoring capabilities, and can generate a reset or different interrupts depending on the failure mode of the system. The watchdog can also monitor autonomous systems driven by the Peripheral Reflex System (PRS).3.6 Communications and Other Digital Peripherals3.6.1 Universal Synchronous/Asynchronous Receiver/Transmitter (USART)The Universal Synchronous/Asynchronous Receiver/Transmitter is a flexible serial I/O module. It supports full duplex asynchronous UART communication with hardware flow control as well as RS-485, SPI, MicroWire and 3-wire. It can also interface with devices sup-porting:•ISO7816 SmartCards•IrDA•I2S3.6.2 Enhanced Universal Asynchronous Receiver/Transmitter (EUART)The Enhanced Universal Asynchronous Receiver/Transmitter supports full duplex asynchronous UART communication with hardware flow control, RS-485 and IrDA support. In EM0 and EM1 the EUART provides a high-speed, buffered communication interface.When routed to GPIO ports A or B, the EUART may also be used in a low-energy mode and operate in EM2. A 32.768 kHz clock source allows full duplex UART communication up to 9600 baud.3.6.3 Inter-Integrated Circuit Interface (I2C)The I2C module provides an interface between the MCU and a serial I2C bus. It is capable of acting as a main or secondary interface and supports multi-drop buses. Standard-mode, fast-mode and fast-mode plus speeds are supported, allowing transmission rates from 10 kbit/s up to 1 Mbit/s. Bus arbitration and timeouts are also available, allowing implementation of an SMBus-compliant system. The interface provided to software by the I2C module allows precise timing control of the transmission process and highly automated trans-fers. Automatic recognition of addresses is provided in active and low energy modes. Note that not all instances of I2C are available in all energy modes.3.6.4 Peripheral Reflex System (PRS)The Peripheral Reflex System provides a communication network between different peripheral modules without software involvement. Peripheral modules producing Reflex signals are called producers. The PRS routes Reflex signals from producers to consumer periph-erals which in turn perform actions in response. Edge triggers and other functionality such as simple logic operations (AND, OR, NOT) can be applied by the PRS to the signals. The PRS allows peripherals to act autonomously without waking the MCU core, saving power.3.6.5 Pulse Density Modulation (PDM) InterfaceThe PDM module provides a serial interface and decimation filter for Pulse Density Modulation (PDM) microphones, isolated Sigma-delta ADCs, digital sensors and other PDM or sigma delta bit stream peripherals. A programmable Cascaded Integrator Comb (CIC) filter is used to decimate the incoming bit streams. PDM supports stereo or mono input data and DMA transfer.3.7 Security FeaturesThe following security features are available on the EFR32FG22:•Secure Boot with Root of Trust and Secure Loader (RTSL)•Cryptographic Accelerator•True Random Number Generator (TRNG)•Secure Debug with Lock/Unlock3.7.1 Secure Boot with Root of Trust and Secure Loader (RTSL)The Secure Boot with RTSL authenticates a chain of trusted firmware that begins from an immutable memory (ROM).It prevents malware injection, prevents rollback, ensures that only authentic firmware is executed, and protects Over The Air updates. For more information about this feature, see AN1218: Series 2 Secure Boot with RTSL.3.7.2 Cryptographic AcceleratorThe Cryptographic Accelerator is an autonomous hardware accelerator which supports AES encryption and decryption with 128/192/256-bit keys, Elliptic Curve Cryptography (ECC) to support public key operations and hashes.Supported block cipher modes of operation for AES include:•ECB (Electronic Code Book)•CTR (Counter Mode)•CBC (Cipher Block Chaining)•CFB (Cipher Feedback)•GCM (Galois Counter Mode)•CBC-MAC (Cipher Block Chaining Message Authentication Code)•GMAC (Galois Message Authentication Code)•CCM (Counter with CBC-MAC)The Cryptographic Accelerator accelerates Elliptical Curve Cryptography and supports the NIST (National Institute of Standards and Technology) recommended curves including P-192 and P-256 for ECDH(Elliptic Curve Diffie-Hellman) key derivation and ECDSA (El-liptic Curve Digital Signature Algorithm) sign and verify operations.Supported hashes include SHA-1, SHA2/224, and SHA-2/256.This implementation provides a fast and energy efficient solution to state of the art cryptographic needs.3.7.3 True Random Number GeneratorThe True Random Number Generator module is a non-deterministic random number generator that harvests entropy from a thermal energy source. It includes start-up health tests for the entropy source as required by NIST SP800-90B and AIS-31 as well as online health tests required for NIST SP800-90C.The TRNG is suitable for periodically generating entropy to seed an approved pseudo random number generator.3.7.4 Secure Debug with Lock/UnlockFor obvious security reasons, it is critical for a product to have its debug interface locked before being released in the field.In addition, the EFR32FG22 also provides a secure debug unlock function that allows authenticated access based on public key cryp-tography. This functionality is particularly useful for supporting failure analysis while maintaining confidentiality of IP and sensitive end-user data.More information on this feature can be found in AN1190: Series 2 Secure Debug.3.8 Analog3.8.1 Analog to Digital Converter (IADC)The IADC is a hybrid architecture combining techniques from both SAR and Delta-Sigma style converters. It has a resolution of 12 bits at 1 Msps and 16 bits at up to 76.9 ksps. Hardware oversampling reduces system-level noise over multiple front-end samples. The IADC includes integrated voltage reference options. Inputs are selectable from a wide range of sources, including pins configurable as either single-ended or differential.3.9 PowerThe EFR32FG22 has an Energy Management Unit (EMU) and efficient integrated regulators to generate internal supply voltages. Only a single external supply voltage is required, from which all internal voltages are created. An optional integrated DC-DC buck regulator can be utilized to further reduce the current consumption. The DC-DC regulator requires one external inductor and one external capaci-tor.The EFR32FG22 device family includes support for internal supply voltage scaling, as well as two different power domains groups for peripherals. These enhancements allow for further supply current reductions and lower overall power consumption.3.9.1 Energy Management Unit (EMU)The Energy Management Unit manages transitions of energy modes in the device. Each energy mode defines which peripherals and features are available and the amount of current the device consumes. The EMU can also be used to implement system-wide voltage scaling and turn off the power to unused RAM blocks to optimize the energy consumption in the target application. The DC-DC regula-tor operation is tightly integrated with the EMU.3.9.2 Voltage ScalingThe EFR32FG22 supports supply voltage scaling for the LDO powering DECOUPLE, with independent selections for EM0 / EM1 and EM2 / EM3. Voltage scaling helps to optimize the energy efficiency of the system by operating at lower voltages when possible. The EM0 / EM1 voltage scaling level defaults to VSCALE2, which allows the core to operate in active mode at full speed. The intermediate level, VSCALE1, allows operation in EM0 and EM1 at up to 40 MHz. The lowest level, VSCALE0, can be used to conserve power fur-ther in EM2 and EM3. The EMU will automatically switch the target voltage scaling level when transitioning between energy modes.3.9.3 DC-DC ConverterThe DC-DC buck converter covers a wide range of load currents, provides high efficiency in energy modes EM0, EM1, EM2 and EM3, and can supply up to 60 mA for device and radio operation. RF noise mitigation allows operation of the DC-DC converter without signifi-cantly degrading sensitivity of radio components. An on-chip supply-monitor signals when the supply voltage is low to allow bypass of the regulator via programmable software interrupt. It employs soft switching at boot and DCDC regulating-to-bypass transitions to limit the max supply slew-rate and mitigate inrush current.3.9.4 Power DomainsThe EFR32FG22 has two peripheral power domains for operation in EM2 and EM3, as well as the ability to selectively retain configura-tions for EM0/EM1 peripherals. A small set of peripherals always remain powered on in EM2 and EM3, including all peripherals which are available in EM4. If all of the peripherals in PD0B are configured as unused, that power domain will be powered off in EM2 or EM3, reducing the overall current consumption of the device. Likewise, if the application can tolerate the setup time to re-configure used EM0/EM1 peripherals on wake, register retention for these peripherals can be disabled to further reduce the EM2 or EM3 current.Table 3.1. Peripheral Power Subdomains3.10 Reset Management Unit (RMU)The RMU is responsible for handling reset of the EFR32FG22. A wide range of reset sources are available, including several power supply monitors, pin reset, software controlled reset, core lockup reset, and watchdog reset.3.11 Core and Memory3.11.1 Processor CoreThe ARM Cortex-M processor includes a 32-bit RISC processor integrating the following features and tasks in the system:•ARM Cortex-M33 RISC processor achieving 1.50 Dhrystone MIPS/MHz•ARM TrustZone security technology•Embedded Trace Macrocell (ETM) for real-time trace and debug•Up to 512 kB flash program memory•Up to 32 kB RAM data memory•Configuration and event handling of all modules•2-pin Serial-Wire debug interface3.11.2 Memory System Controller (MSC)The Memory System Controller (MSC) is the program memory unit of the microcontroller. The flash memory is readable and writable from both the Cortex-M33 and LDMA. In addition to the main flash array where Program code is normally written the MSC also provides an Information block where additional information such as special user information or flash-lock bits are stored. There is also a read-only page in the information block containing system and device calibration data. Read and write operations are supported in energy modes EM0 Active and EM1 Sleep.3.11.3 Linked Direct Memory Access Controller (LDMA)The Linked Direct Memory Access (LDMA) controller allows the system to perform memory operations independently of software. This reduces both energy consumption and software workload. The LDMA allows operations to be linked together and staged, enabling so-phisticated operations to be implemented.。

AP8263 PDF文档
CURRENT MODEDESCRIPTIONFEATURESAP8263 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications in sub 30W range.PWM switching frequency at normal operation is externally programmable and trimmed to tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss. Lower standby power and higher conversion efficiency is thus achieved.The internal slope compensation improves system large signal stability and reduces the possible subharmonic oscillation at high PWM duty cycleoutput. Leading-edge blanking on current sense(CS) input removes the signal glitch due to snubber circuit diode reverse recovery and thus greatly reduces the external component count and system cost in the design.Excellent EMI performance is achieved withproprietary frequency shuffling technique together with soft switching control at the totem pole gate drive output.The AP8263 is available in SOT26、SOP8 and DIP8 Package● Proprietary Frequency Shuffling Technology for Improved EMI Performance.● Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design ● Audio Noise Free Operation● External Programmable PWM Switching Frequency● Internal Synchronized Slope Compensation ● Low V DD Startup Current and Low Operating Current (1.4mA)● Leading Edge Blanking on Current Sense Input ● Owning soft start-up function● Good Protection Coverage With Auto Self- Recovery● V DD Over Voltage Clamp and Under Voltage Lockout with Hysteresis (UVLO)● Gate Output Maximum Voltage Clamp (18V) ●Proprietary Line Input CompensatedCycle-by-Cycle Over-current Threshold Setting For Constant Output Power Limiting Over Universal Input Voltage Range. ● Overload Protection (OLP)●Available in SOT26、SOP8 and DIP8 PackageAPPLICATION● Offline AC/DC flyback converter for ● Battery Charger ● Power Adaptor● Set-Top Box Power Supplies ●Open-frame SMPSORDERING INFORMATIONPackage Type Part Number SOT-26 E6 AP8263E6R A8263E6VR DIP8 P8 AP8263P8U AP8263P8VU SOP-8 M8AP8263M8R AP8263M8VRNoteR: Tape & Reel V: Green PackageAiT provides all Pb free products Suffix “ V “ means Green PackageTYPICAL APPLICATIONCURRENT MODE PIN DESCRIPTIONTop View Top View Top ViewPin #Symbol FunctionSOT-26 DIP8 SOP-81 8 8 GND Ground2 7 7 FB Feedback input pin.

The extended burst mode control greatly reduces the standby power consumption and helps the design easily meet the international power conservation requirements.Startup Current and Start up ControlStartup current of AP8263 is designed to be very low so that V DD could be charged up above UVLO threshold level and device starts up quickly. A large value startup resistor can therefore be used to minimize the power loss yet provides reliable startup in application. For AC/DC adaptor with universal input range design, a 2 MΩ, 1/8 W startup resistor could be used together with a V DD capacitor to provide a fast startup and low power dissipation solution.Operating CurrentThe Operating current of AP8263 is low at 1.4mA. Good efficiency is achieved with AP8263 low operating current together with extended burst mode control features.Soft-Start upDuring the converter start up time, the primary current limitation is progressively increased to the maximum value. In this way the stress on the secondary diode is considerably reduced. it also help to prevent transformer saturation. The soft-start up time lasts 2 ms and the featuer is implemented for every attempt of start up converter.Frequency shuffling for EMI improvementThe frequency Shuffling/jittering (switching frequency modulation) is implemented in AP8263. The oscillation frequency is modulated with a random source so that the tone energy is spread out. The spread spectrum minimizes the conduction band EMI and therefore reduces system design challenge.Extended Burst Mode OperationAt zero load or light load condition, majority of the power dissipation in a switching mode power supply is from switching loss on the MOSFET transistor, the core loss of the transformer and the loss on the snubber circuit. The magnitude of power loss is in proportion to the number of switching events within a fixed period of time. Reducing switching events leads to the reduction on the power loss and thus conserves the energy.CURRENT MODEAP8263 self adjusts the switching mode according to the loading condition. At from no load to light/medium load condition, the FB input drops below burst mode threshold level. Device enters Burst Mode control. The Gate drive output switches only when V DD voltage drops below a preset level and FB input is active to output an on state. Otherwise the gate drive remains at off state to minimize the switching loss and reduces the standby power consumption to the greatest extend. The frequency control also eliminates the audio noise at any loading conditions.Oscillator OperationA resistor connected between RI and GND sets the constant current source to charge/discharge the internal cap and thus the PWM oscillator frequency is determined. The relationship between RI and switching frequency follows the below equation within the specified RI in Kohm range at nominal loading operational condition.Current Sensing and Leading Edge BlankingCycle-by-Cycle current limiting is offered in AP8263 current mode PWM control. The switch current is detected by a sense resistor into the sense pin. An internal leading edge blanking circuit chops off the sense voltage spike at initial MOSFET on state due to Snubber diode reverse recovery so that the external RC filtering on sense input is no longer required. The current limit comparator is disabled and thus cannot turn off the external MOSFET during the blanking period. PWM duty cycle is determined by the current sense input voltage and the FB input voltage.Internal Synchronized Slope CompensationBuilt-in slope compensation circuit adds voltage ramp onto the current sense input voltage for PWM generation. This greatly improves the close loop stability at CCM and prevents the sub-harmonic oscillation and thus reduces the output ripple voltage.Gate DriveAP8263 Gate is connected to an external MOSFET gate for power switch control. Too weak the gate drive strength results in higher conduction and switch loss of MOSFET while too strong gate drive output compromises the EMI. A good tradeoff is achieved through the built-in totem pole gate design with right output strength and dead time control. The low idle loss and good EMI system design is easier to achieve with thisCURRENT MODEdedicated control scheme. An internal 18V clamp is added for MOSFET gate protection at higher than expected V DD input.Protection ControlsGood power supply system reliability is achieved with its rich protection features including Cycle-by- Cycle current limiting (OCP), Over Load Protection (OLP) and over voltage clamp, Under Voltage Lockout on V DD (UVLO).With Proprietary technology, the OCP threshold tracks PWM Duty cycles and is line voltage compensated to achieve constant output power limit over the universal input voltage range with recommended reference design.At overload condition when FB input voltage exceeds power limit threshold value for more than TD_PL, control circuit reacts to shut down the output power MOSFET. Device restarts when V DD voltage drops below UVLO limit.V DD is supplied by transformer auxiliary winding output. It is clamped when V DD is higher than threshold value. The power MOSFET is shut down when V DD drops below UVLO limit and device enters power on start-up sequence thereafter.CURRENT MODECURRENT MODEPACKAGE INFORMATIONDimension in SOT-26 (Unit: mm)Symbol Min MaxA 1.050 1.250A1 0.0000.100A2 1.050 1.150b 0.3000.500c 0.1000.200D 2.820 3.020E 1.500 1.700E1 2.650 2.950e 0.950(BSC)e1 1.800 2.000L 0.3000.600θ 0°8°CURRENT MODEDimension in SOP-8 (Unit: mm)Symbol Min MaxA 1.350 1.750A1 0.100 0.250A2 1.350 1.550b 0.330 0.510c 0.170 0.250D 4.700 5.100E 3.800 4.000E1 5.800 6.200e 1.270(BSC)L 0.400 1.270θ 0° 8°CURRENT MODEDimension in DIP8 (Unit: mm)Symbol Min MaxA 3.710 4.310A1 0.510 -A2 3.200 3.600B 0.380 0.570B1 1.524(BSC)C 0.204 0.360D 9.000 9.400E 6.200 6.600E1 7.320 7.920e 2.540(BSC)L 3.000 3.600E2 8.400 9.000CURRENT MODEIMPORTANT NOTICEAiT Semiconductor Inc.
