After capturing several images, Atmel proprietary software can recon-struct a full 8-bit fingerprint image.The AT77C102B has a small surface combined with CMOS technology, and a Chip-on-Board package assembly. These facts contribute to a low-cost device.The device delivers a programmable number of images per second, while an integrated analog-to-digital converter delivers a digital signal adapted to interfaces such as an EPP parallel port, a USB microcontroller or directly to microprocessors. No frame grabber or glue interface is there-fore necessary to send the frames. These facts make AT77C102B an easy device to include in any system for identification or verification applications.Table 3-1.Absolute Maximum RatingsParameterSymbol CommentsValue Positive supply voltage V CC GND to 4.6Note: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

This is to ensure that the output drivers of the data are not driving cur-rent, so as to reduce the noise level on the power supply.Figure 3-5.AT77C102B Block Diagram3.1Functional DescriptionThe circuit is divided into two main sections: sensor and data conversion. One particular column among 280 plus one is selected in the sensor array (1), then each pixel of the selected column sends its electrical information to the amplifiers (2) [one per line], then two lines at a time are selected (odd and even) so that two particular pixels send their information to the input of two 4-bit analog-to-digital converters (3), so two pixels can be read for each clock pulse (4).115364C–BIOM–3/07AT77C102BFigure 3-6.Functional Description3.2SensorEach pixel is a sensor in itself. The sensor detects a temperature difference between the begin-ning of an acquisition and the reading of the information: this is the integration time. The integration time begins with a reset of the pixel to a predefined initial state. Note that the integra-tion time reset has nothing to do with the reset of the digital section.Then, at a rate depending on the sensitivity of the pyroelectric layer, on the temperature varia-tion between the reset and the end of the integration time, and for the duration of the integration time, electrical charges are generated at the pixel level.3.3Analog-to-digital Converter/ Reconstructing an 8-bit Fingerprint ImageAn analog-to-digital converter (ADC) is used to convert the analog signal coming from the pixel into digital data that can be used by a processor.As the data rate for the parallel port and the USB is in the range of 1 MB per second, and at least a rate of 500 frames per second is needed to reconstruct the image with a fair sweeping speed of the finger, two 4-bit ADCs have been used to output two pixels at a time on one byte.3.4Start SequenceA reset is not necessary between each frame acquisition.The start sequence must consist in:1.Setting the RST pin to high.2.Setting the RST pin to low.3.Sending 4 clock pulses (due to pipe-line).4.Sending clock pulses to skip the first frame.Note that after a reset it is recommended to skip the first 200 slices to stabilize the acquisition.Figure 3-7.Start Sequence125364C–BIOM–3/07AT77C102B3.5Reading the FramesA frame consists of 280 true columns plus one dummy column of eight pixels. As two pixels are output at a time, a system must send 281 x 4 = 1124 clock pulses to read one frame.Reset must be low when reading the frames.3.6Read One Byte/Output EnableThe clock is taken into account on its falling edge and data is output on its rising edge.For each clock pulse, after the start sequence, a new byte is output on the Do0-3 and De0-3 pins. This byte contains two pixels: 4-bit on Do0-3 (odd pixels), 4-bit on De0-3 (even pixels).To output the data, the output enable (OE) pin must be low. When OE is high, the Do0-3 and De0-3 pins are in high-impedance state. This facilitates an easy connection to a microprocessor bus without additional circuitry since the data output can be enabled using a chip select signal. Note that the AT77C102B always sends data: there is no data exchange to switch to read/write mode.3.7Power Supply NoiseIMPORTANT: When a falling edge is applied on OE (that is when the Output Enable becomes active), then some current is drained from the power supply to drive the eight outputs, producing some noise. It is important to avoid such noise just after the PCLK clock’s falling edge, when the pixels’ information is evaluated: the timing diagram (Figure 3-2) and time T NOOE define the inter-val time when the power supply must be as quiet as possible.3.8Video OutputAn analog signal is also available on pins AVE and AVO. Note that video output is available one clock pulse before the corresponding digital output (one clock pipe-line delay for the analog to digital conversion).3.9Pixel OrderAfter a reset, pixel 1 is located on the upper left corner, looking at the chip with bond pads to the right. For each column of eight pixels, pixels 1, 3, 5 and 7 are output on odd data Do0-3 pins, and pixels 2, 4, 6 and 8 are output on even data De0-3 pins. The Most Significant Bit (MSB) is bit 3, and the Least Significant Bit is bit 0.Figure 3-8.Pixel Order135364C–BIOM–3/07AT77C102B3.10Synchronization: The Dummy ColumnA dummy column has been added to the sensor to act as a specific pattern to detect the first pixel. Therefore, 280 true columns plus one dummy column are read for each frame.The four bytes of the dummy column contain a fixed pattern on the first two bytes, and tempera-ture information on the last two bytes.Note:x represents 0 or 1The sequence 111X0000 111X0000 appears on every frame (exactly every 1124 clock pulses), so it is an easy pattern to recognize for synchronization purposes.3.11ThermometerThe dummy bytes DB3 and DB4 contain some internal temperature information.The even nibble nnnn in DB3 can be used to measure an increase or decrease of the chip’s tem-perature, using the difference between two measures of the same physical device. The following table gives values in Kelvin.Table 1.

This enables enough contrast to obtain a proper fingerprint reconstruction.3.12Integration Time and Clock JitterThe AT77C102B is not very sensitive to clock jitters (clock variations). The most important requirement is a regular integration time that ensures the frame reading rate is also as regular as possible, so as to obtain consistent fingerprint slices.If the integration time is not regular, the contrast can vary from one frame to another.Note that it is possible to introduce some waiting time between each set of 1124 clock pulses, but the overall time of one frame read must be regular. This waiting time is generally the time needed by the processor to perform some calculation over the frame (to detect the finger, for instance).Figure 3-9.Read One FrameFigure 3-10.Regular Integration Time3.13Power Management 3.14Nap ModeSeveral strategies are possible to reduce power consumption when the device is not in use.The simplest and most efficient is to cut the power supply using external means.A nap mode is also implemented in the AT77C102B. To activate this nap mode, you must:1.Set the reset RST pin to high. By doing this, all analog sections of the device are inter-nally powered down.2.Set the clock PCLK pin to high (or low), thus stopping the entire digital section.3.Set the TPE pin to low to stop the temperature stabilization feature.4.Set the Output Enable OE pin to high, so that the output is forced in HiZ.155364C–BIOM–3/07AT77C102BFigure 3-11.Nap ModeIn nap mode, all internal transistors are in shut mode. Only leakage current is drained in the power supply, generally less than the tested value.3.15Static Current ConsumptionWhen the clock is stopped (set to 1) and the reset is low (set to 0), the device’s analog sections drain some current, whereas, if the outputs are connected to a standard CMOS input, the digital section does not consume any current (no current is drained in the I/O). In this case the typical current value is 5 mA. This current does not depend on the voltage (it is almost the same from 3 to 3.6V).3.16Dynamic Current ConsumptionWhen the clock is running, the digital sections, and particularly the outputs if they are heavily loaded, consume current. In any case, the current should be less than the testing machine (120 pF load on each I/O), and a maximum of 50 pF is recommended.The AT77C102B, running at about 1 MHz, consumes less than 7 mA on the V CC pin.3.17Temperature Stabilization Power Consumption (TPP Pin)When the TPE pin is set to 1, current is drained via the TPP pin. The current is limited by the internal equivalent resistance given in Table 3-4 on page 6 and a possible external resistor. Most of the time, TPE is set to 0 and no current is drained in TPP. When the image contrast becomes low because of a low temperature differential (less than 1 Kelvin), then it is recom-mended to set TPE to 1 for a short time so that the dissipated power in the chip elevates the temperature, allowing contrast recovery. The necessary time to increase the chip’s temperature by one Kelvin depends on the dissipated power, the thermal capacity of the silicon sensor and the thermal resistance between the sensor and its surroundings. As a rule of thumb, dissipating 300 mW in the chip elevates the temperature by 1 Kelvin in one second. With the 30Ω typical value, 300 mW is 3V applied on TPP. If the power supply is 3.6V, an external resistor must be added in the application to limit the current under 100 mA.165364C–BIOM–3/07AT77C102B4.Packaging: Mechanical DataFigure 4-2.Product Reference: AT77C102B-CB01YV — Bottom View (all dimensions in mm)175364C–BIOM–3/07AT77C102BFigure 4-3.Product Reference: AT77C102B-CB02YV4.1Package Information4.1.1Electrical DisturbancesWhen looking at the fingerchip device from the top with the glob top to the right, the right edge must never be in contact with customer casing or any component to avoid electrical disturbances.Figure 4-4.Epoxy OverflowMaximum epoxy overflow width: 0.55 mm on the die edge.Maximum epoxy overflow thickness: 0.33 mm.Note:Refer to Figure 4-1 on page 16.185364C–BIOM–3/07AT77C102B5.Ordering Information5.1Package Device195364C–BIOM–3/07AT77C102BRevision HistoryDoc.

Designed specifically for battery-operated systems, the devices’ CMOS construction minimizes ground current, extending battery life. Total supply current is typically 50µA at full load (20 to 60 times lower than in bipolar regulators).The devices’ key features include low noise operation,low dropout voltage – typically 85mV (TC1054),180mV (TC1055) and 270mV (TC1186) at full load —and fast response to step changes in load. An error output (ERROR) is asserted when the devices are out-of-regulation (due to a low input voltage or excessive output current). ERROR can be used as a low battery warning or as a processor RESET signal (with the addition of an external RC network). Supply current is reduced to 0.5µA (max), with both V OUT and ERROR disabled when the shutdown input is low. The devices incorporate both over-temperature and over-current protection.The TC1054, TC1055 and TC1186 are stable with an output capacitor of only 1µF and have a maximum output current of 50mA, 100mA and 150mA,respectively. For higher output current regulators,please refer to the TC1173 (I OUT = 300mA) data sheet (DS21632).Package TypeTC1054TC1055TC1186V OUT GND1µF+V IN V IN V OUT15243SHDN Shutdown Control(from Power Control Logic)ERRORERROR1M ΩNOTE: 5-Pin SOT-23 is equivalent to the EIAJ (SC-74A)514235-Pin SOT-23TC1054TC1055TC1186V OUT ERRORSHDN GNDV IN50mA, 100mA and 150mA CMOS LDOs with Shutdownand ERROR OutputTC1054/TC1055/TC1186DS21350D-page 2© 2007 Microchip Technology Inc.1.0ELECTRICALCHARACTERISTICSAbsolute Maximum Ratings †Input Voltage....................................................................6.5V Output Voltage .....................................(-0.3V) to (V IN + 0.3V)Power Dissipation .........................Internally Limited (Note 6)Maximum Voltage on Any Pin ...................V IN +0.3V to -0.3V Operating Junction Temperature Range..-40°C < T J < 125°C Storage Temperature.....................................-65°C to +150°C† Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.

If there is a large distance between the input supply and the LDO regulator, some input capacitance is necessary for proper operation. A 1µF capacitor connected from V IN to ground is recommended for most applications.3.2Ground Terminal (GND)Connect the unregulated input supply ground return to GND. Also connect the negative side of the 1µF typical input decoupling capacitor close to GND and the negative side of the output capacitor C OUT to GND.3.3Shutdown Control Input (SHDN)The regulator is fully enabled when a logic-high is applied to SHDN. The regulator enters shutdown when a logic-low is applied to SHDN. During shutdown,output voltage falls to zero, ERROR is open-circuited and supply current is reduced to 0.5µA (max).3.4Out Of Regulation Flag (ERROR)ERROR goes low when V OUT is out-of-tolerance by approximately -5%.3.5Regulated Voltage Output (V OUT )Connect the output load to V OUT of the LDO.

Unlike bipolar regulators, the TC1054, TC1055 and TC1186 supply current does not increase with load current.Figure 4-1 shows a typical application circuit, where the regulator is enabled any time the shutdown input (SHDN) is at or above V IH , and shutdown (disabled)when SHDN is at or below V IL . SHDN may be controlled by a CMOS logic gate or I/O port of a microcontroller. If the SHDN input is not required, it should be connected directly to the input supply. While in shutdown, supply current decreases to 0.05µA (typical), V OUT falls to zero volts, and ERROR is open-circuited.FIGURE 4-1:Typical Application Circuit.4.1ERROR Open-Drain OutputERROR is driven low whenever V OUT falls out of regulation by more than -5% (typical). This condition may be caused by low input voltage, output current limiting or thermal limiting. The ERROR threshold is 5%below rated V OUT , regardless of the programmed output voltage value (e.g. ERROR = V OL at 4.75V (typ.)for a 5.0V regulator and 2.85V (typ.) for a 3.0V regulator). ERROR output operation is shown in Figure 4-2.Note that ERROR is active when V OUT falls to V TH and inactive when V OUT rises above V TH by V HYS .As shown in Figure 4-1, ERROR can be used either as a battery low flag or as a processor RESET signal (with the addition of timing capacitor C 2). R 1 x C 2 should be chosen to maintain ERROR below V IH of the processor RESET input for at least 200ms to allow time for the system to stabilize. Pull-up resistor R 1 can be tied to V OUT , V IN or any other voltage less than (V IN + 0.3V).FIGURE 4-2:Error Output Operation.4.2Output CapacitorA 1µF (minimum) capacitor from V OUT to ground is recommended. The output capacitor should have an effective series resistance greater than 0.1Ω and less than 5.0Ω, with a resonant frequency above 1MHz. A 1µF capacitor should be connected from V IN to GND if there is more than 10 inches of wire between the regulator and the AC filter capacitor or if a battery is used as the power source. Aluminum electrolytic or tantalum capacitor types can be used (Since many aluminum electrolytic capacitors freeze at approxi-mately -30°C, solid tantalums are recommended for applications operating below -25°C.). When operating from sources other than batteries, supply-noise rejection and transient response can be improved by increasing the value of the input and output capacitors and employing passive filtering techniques.or RESETTC1054 TC1055 TC1186V OUTSHDN GNDERROR+V IN V OUTShutdown Control (to CMOS Logic or Tie to V IN if unused)1µF+Battery+0.2µF C 2C 2 Required Only if ERROR is used as a Processor RESET Signal(See Text)R 1 1MW V+BATTLOW 1µF C 1V THV OUT ERRORV IH V OLHYSTERESIS (V H )t DELAYTC1054/TC1055/TC1186DS21350D-page 10© 2007 Microchip Technology Inc.5.0THERMAL CONSIDERATIONS5.1Thermal ShutdownIntegrated thermal protection circuitry shuts the regulator off when die temperature exceeds 160°C.The regulator remains off until the die temperature drops to approximately 150°C.5.2Power DissipationThe amount of power the regulator dissipates is primarily a function of input voltage, output voltage and output current. The following equation is used to calculate worst case actual power dissipation:EQUATION 5-1:The maximum allowable power dissipation (Equation 5-2) is a function of the maximum ambient temperature (T A MAX ), the maximum allowable die temperature (T J MAX ) and the thermal resistance from junction-to-air (θJA ). The 5-Pin SOT-23 package has a θJA of approximately 220°C/Watt.EQUATION 5-2:Equation 5-1 can be used in conjunction with Equation 5-2 to ensure regulator thermal operation is within limits.For example:Actual power dissipation:Maximum allowable power dissipation:In this example, the TC1054 dissipates a maximum of 20.7mW; below the allowable limit of 318mW. In a similar manner, Equation 5-1 and Equation 5-2 can be used to calculate maximum current and/or input voltage limits.5.3Layout ConsiderationsThe primary path of heat conduction out of the packageis via the package leads. Therefore, layouts having a ground plane, wide traces at the pads and wide power supply bus lines combine to lower θJA and, therefore,increase the maximum allowable power dissipation limit.Where:P D V IN MAX V OUT MIN I LOAD MAX= Worst case actual power dissipation = Minimum regulator output voltage = Maximum output (load) current= Maximum voltage on V INP D V INMAX V OUTMIN –()I LOADMAX≈Where all terms are previously defined.P DMAX T JMAX T AMAX –()θJA-------------------------------------------=Given:V IN MAX = 3.0V +5%V OUT MIN = 2.7V – 2.5%I LOAD MAX = 40mA T J MAX = +125°C T A MAX = +55°C Find:1.Actual power dissipation2.Maximum allowable dissipationP D V INMAX V OUTMIN –()I LOADMAX≈ 3.0 1.05×() 2.70.975×()–[]4010-3×=20.7mW=P DMAX T JMAX T AMAX –()θJA-------------------------------------------=12555–()220-------------------------=318mW=© 2007 Microchip Technology Inc.DS21350D-page 11TC1054/TC1055/TC11866.0PACKAGING INFORMATION6.1Package Marking Information(V)TC1054Code TC1055Code TC1186Code 1.8CY DY PY 2.5C1D1P12.6CT DT PV 2.7C2D2P22.8CZ DZ PZ 2.85C8D8P83.0C3D3P33.3C4D4P53.6C9D9P94.0C0D0P05.0C6D6P75142312345-Pin SOT-23represents part number code +temperature range and voltage&12represents year and quarter code 3represents lot ID number4TC1054/TC1055/TC1186DS21350D-page 12© 2007 Microchip Technology Inc.TC1054/TC1055/TC1186 APPENDIX A:REVISION HISTORYRevision D (February 2007)•Corrected standard output voltages on page1and in “Product Identification System”.•Added T DELAY parameter in DC Characteristicstable in “Electrical Characteristics”.•Changes to Figure4-2.• “Packaging Information”: Corrected SOT-23Packaging Informaton.Revision C (March 2003)•Undocumented changes.Revision B (May 2002)•Undocumented changes.Revision A (March 2002)•Original Release of this Document.© 2007 Microchip Technology Inc.DS21350D-page 13TC1054/TC1055/TC1186NOTES:DS21350D-page 14© 2007 Microchip Technology Inc.© 2007 Microchip Technology Inc.DS21350D-page 15TC1054/TC1055/TC1186PRODUCT IDENTIFICATION SYSTEMTo order or obtain information, e.g., on pricing or delivery, refer to the factory or the listed sales office .

BATTERY MANAGEMENT Jul 09, 1998 Switch-Mode Battery Charger Delivers 5AThe fast-charge controller IC3 (Figure 1) normally directs current to the battery via an external pnp transistor. In this circuit, the transistor is replaced with a 5A switching regulator (IC1) that delivers equivalent power with higher efficiency.Figure 1. By controlling the PWM duty cycle of switching regulator IC1, the fast-charge controller (IC3) makes efficient delivery of the battery's charging current.IC1 is a 5A buck switching regulator whose output is configured as a current source. Its internal power switch (an npn transistor) is relatively efficient because V CE(SAT) is small in comparison with the 15V-to-40V inputs. (For applications that require 2A or less, the low-saturation, non-Darlington power switch of a MAX726 offers better efficiency.)R6 senses the battery-charging current and enables IC3 to generate an analog drive signal at DRV. The signal is first attenuated by the op amp to assure stability by reducing gain in the control loop. It then drives IC1's compensation pin (VC), which gives direct access to the internal PWM comparator. IC3 thus controls the charging current via the PWM duty cycle of IC1. The Q1 buffer provides current to the DRV input.Loop stability is also determined by the feedback loop's dominant pole, set by C4 at the CC terminal of IC3. If you increase the value of the battery filter capacitor (C5), you should make a proportional increase in the value of C4. Lower values, however, assure good transient response. If your application produces load transients during the fast-charge cycle, check the worst-case response to a load step. To assure proper termination of the charge, battery voltage should settle within 2msec to 5mV times N (where N is the number of battery cells).

TC1070/TC1071/TC1187
1.0 ELECTRICAL CHARACTERISTICS
† Notice: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.
Description:
The TC1070, TC1071 and TC1187 devices are adjustable LDOs designed to supersede a variety of older (bipolar) voltage regulators. Total supply current is typically 50 µA at full load (20 to 60 times lower than in bipolar regulators). The devices’ key features include ultra low-noise operation, very low dropout voltage – typically 85 mV (TC1070), 180 mV (TC1071) and 270 mV (TC1187) at full load and fast response to step changes in load. Supply current is reduced to 0.5 µA (maximum) when the shutdown input is low. The devices incorporate both overtemperature and overcurrent protection. Output voltage is programmed with a simple resistor divider from VOUT to ADJ to GND. The TC1070, TC1071 and TC1187 devices are stable with an output capacitor of only 1 µF and have a maximum output current of 50 mA, 100 mA and 150 mA, respectively. For higher output versions please see the TC1174 (IOUT = 300 mA) data sheet (DS21363).

Load regulation is tested over a load range from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value. Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to Ilmax at VIN = 6V for T = 10 ms. The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction-to-air (i.e., Ta, Tj, ja). Exceeding the maximum allowable power dissipation causes the device to initiate thermal shutdown. Please see Section 5.0 “Thermal Considerations” for more details. The minimum VIN has to justify the conditions: VIN VR + VDROPOUT and VIN 2.7V for IL = 0.1 mA to IOUTMAX.
