1.3 Description of the Power Stages
OUT1... OUT6
6 non-inverting low side power switches for nominal currents up to 2.2A. Control is possible by input pins, by the µsec-bus or via SPI. For TJ = 25°C the on-resistance of the power switches is below 400mΩ. An integrated zener diode limits the output voltage to 70V typically.
A protection for inverse current is implemented for OUT1... OUT4 for use as stepper-motor control.

SP6223中文资料
DESCRIPTION■ SMPS Post-Regulator ■ DC-to-DC Modules ■ Medical Devices ■ Data Cable ■ PagersFEATURESAPPLICATIONSThe SP6222 and SP6223 are CMOS LDOs designed to meet a broad range of applications that require accuracy,speed and ease of use. These LDOs offer extremely low quiescent current which only increases slightly under load,thus providing advantages in ground current performance over bipolar LDOs. The LDOs handle an extremely wide load range and guarantee stability with a 1μF ceramic output capacitor. They have excellent low frequency PSRR,not found in other CMOS LDOs and thus offer exceptional Line Regulation. High frequency PSRR is 55dB (typical)at 1kHz. Load Regulation is excellent and temperature stability is comparable to bipolar LDOs. An enable feature is provided on all versions. The SP6222/6223 is available in fixed and adjustable output voltage versions in industry standard SC70 and SOT23 packages.TYPICAL APPLICATION CIRCUITVery low Dropout Voltage: 200mV typ (150mA load) High Output Setpoint Accuracy of 2% Very low Input Voltages Down to 1.6VPower-saving Shutdown Mode of 150nA (typ) Fast Turn-on (90μs) and Turn-off (90μs)Extremely low Quiescent Current of 14μA (typ) Very Tight Line regulation, 0.2%/V Load Regulation 0.125 mV/mA Thermal Shutdown ProtectionLow Noise Output, 100μV RMS With 10nF Bypass Fixed or Adjustable Output Versions AvailableAvailable in RoHS Compliant, Lead Free Packages:SC70 and SOT23■ Cellular Telephones■ Laptop, Notebooks and Palmtop Computers ■ Battery-Powered Equipment ■ Consumer/ Personal Electronics3.0VENABLEELECTRICAL CHARACTERISTICSABSOLUTE MAXIMUM RATINGSThese are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.Storage Temperature...........................-65°C to +150°C Junction Temperature (T J )....................-40°C to +125°C Lead Temperature (soldering 5s).........................300°C Supply Input Voltage (V IN ).............................-2V to 6V Output Voltage (V OUT ).........................-0.6V to V IN +1V Enable Input Voltage (V EN )............................-2V to 7V Power Dissipation (P D )..........Internally Limited, Note 1Unless otherwise specified: V IN = V OUT + 0.3V to 4.5V, C OUT = 1μF ceramic, C IN = 1μF ceramic, I OUT =100μA, T A = 25°C.Bold values apply over the full operating temperature range (-40°C to 125°C).Note 1.The maximum allowable power dissipation at any T A (ambient temperature) is P D (MAX) = (T J (MAX)– T A ) /θJA . Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The θJA of the SP6222/23 (SC-70-5) is 330°C/W mounted on a PC board with minimum copper area (see “Thermal Considerations” section for further details).Note 2.Minimum V IN must meet 2 conditions: V IN >1.6V and V IN > {V OUT + DOV}Note 3.Dropout Voltage DOV is defined as the input to output differential at which the output voltage drops2% below its nominal value measured at 1V differential. The DOV specification is not applicable to output voltages less than 2.7V.ELECTRICAL CHARACTERISTICSUnless otherwise specified: VIN = VOUT+ 0.3V to 4.5V, COUT= 1μF ceramic, CIN= 1μF ceramic, IOUT=100μA, TA= 25°C.Bold values apply over the full operating temperature range (-40°C to 125°C).General OverviewThe SP6222 and SP6223 are CMOS LDOs designed to meet a broad range of low voltage applications that require accuracy and ease of use. The SP6222 offers a 50mA output current while the SP6223 offers an output current of 150mA. The SP6222 is available in a 2.5V or 3.0V fixed output along with an adjustable output version. The SP6223 is offered in an adjustable output only. These LDOs have a minimum input voltage of only 1.6V and a maximum input voltage of 4.5V. The output voltage can be programmed to as low as 0.9V and have a maximum dropout voltage rating of 100mV for the SP6222 and 300mV for the SP6223. Both devices are equipped with an enable (EN) input for very low current (10nA typical) shutdown mode.Enable / Shutdown OperationThe SP6222/6223 is turned on by providing 1.6V or greater to the EN pin. To place the device into shutdown pull the EN pin below 0.4V. If this feature is not required connect EN to input supply to always enable the device whenever power is applied.Input / Output CapacitorThe SP6222/6223 is designed to operate using very small ceramic capacitors. The minimum input and output capacitor value for stable operation is 1.0μF. The output capacitor value may be increased without limit to improve transient response. Place these capacitors as close as possible to the device.Bypass (BYP) CapacitorThe fixed output versions offer a BYP pin to decouple the bandgap reference. Connecting an external 10nF capacitor from BYP to GND can reduce output noise. If output noise is not a concern the BYP pin may be left open. When a bypass capacitor is used the turn on time is slower. See the following turn on time plots for various BYP capacitor values. The adjustable output version does not offer this BYP input. Adjustable RegulatorThe output of the device can be programmed to a specific voltage by using two external resistors connected to the ADJ pin (see Typical Application Circuit for Adjustable output). The resistors set APPLICATION INFORMATIONthe output voltage based on the following equation:V OUT = V REF *(R1/R2 + 1)Resistor values are not critical because the ADJ (adjust) pin has a high impedance, but for best performance use resistor values of 470K Ω or less.Thermal ConsiderationsThe SP6222/6223 is designed to provide 50mA -150mA of continuous current in a tiny package. Maximum power dissipation can be calculated based on the output current and the voltage drop across the part. To determine the maximum power dissipation of the package, use the junction-to-ambient thermal resistance of the device and the following equation:P D(MAX) = (T J(max) – T A ) / θJAT J(max) is the maximum junction temperature of the die and is 125o C.T A is the ambient temperature. θJA is the junction-to-ambient thermal resistance of the package. The SOT-23 package has a θJA of approximately 191o C/W and the SC70 package has a θof approximately 330o C/W.The actual power dissipation of the regulator circuit can be determined by using the simplified equation:P D = (V IN – V OUT ) * I OUTTo prevent the device from entering thermal shutdown, maximum power dissipation cannot be exceeded.Layout ConsiderationsThe primary path of heat conduction out of the package is via the package leads. Therefore, careful consideration must be taken into account for optimizing layout.1.Attaching the part to a large copper footprint will enable better heat transfer from the device, especially where there are internal ground and power planes.2.Place the input and output capacitors close to the device for optimal transient response and device behavior.3.Connect all ground connections directly to the ground plane. In case there is no ground plane,connect to a common ground point before connecting to board ground.APPLICATION INFORMATIONAPPLICATION INFORMATIONVoutIout @ 100mA/divSP6223 1.2Vout fixed Cin = Cout = 1.0uF Cer Iout = 100uA to 150mASP6223 1.2Vout fixed Cin = Cout = 1.0uF Cer Iout = 100uA to 150mAVoutIout @ 100mA/divIout @ 100mA/divSP6223 1.2Vout fixed Cin = Cout = 1.0uF Cer Iout = 100uA to 100mAVoutSP6223 1.2Vout fixed Cin = Cout = 1.0uF Cer Iout = 100uA to 100mAVoutLoad Transient Response, 100μA to 150mA,Vin = 1.6VLoad Transient Response, 100Vin = 3.3VLoad Transient Response, 100Vin = 1.6VLoad Transient Response, 100Vin = 3.3VAPPLICATION INFORMATIONIout @ 100mA/divSP6223 1.2Vout fixed Cin = Cout = 1.0uF Cer Iout = 100uA to 50mAVoutVoutIout @ 100mA/divSP6223 1.2Vout fixed Cin = Cout = 1.0uF Cer Iout = 100uA to 50mASP6222 2.5V fixedVin = 3.0V, Iout = 10mA Cbyp = openEnableVoutSP6222 2.5V fixedVin = 3.0V, Iout = 50mA Cbyp = openEnableLoad Transient Response, 100Vin = 1.6VLoad Transient Response, 100Vin = 3.3VTurn on time, Vin = 3.0V, Iout = 10mA, CBYP = OpenTurn on time, Vin = 3.0V, Iout = 50mA, CBYP = OpenAPPLICATION INFORMATIONSP6222 2.5V fixedVin = 3.0V, Iout = 10mA Cbyp = 1nFVoutEnableSP6222 2.5V fixedVin = 3.0V, Iout = 50mA Cbyp = 1nF VoutEnableSP6222 2.5V fixedVin = 3.0V, Iout = 10mA Cbyp = 10nFVoutEnableSP6222 2.5V fixedVin = 3.0V, Iout = 50mA Cbyp = 10nFEnableTurn on time, Vin = 3.0V, Iout = 10mA,CBYP = 1nFTurn on time, Vin = 3.0V, Iout = 50mA,CBYP = 1nFTurn on time, Vin = 3.0V, Iout = 10mA,CBYP = 10nFTurn on time, Vin = 3.0V, Iout = 50mA,CBYP = 10nFAPPLICATION INFORMATIONSP6222 2.5V fixedVin = 3.0V, Iout = 10mA Cbyp = 100nFVoutEnableVoutSP6222 2.5V fixedVin = 3.0V, Iout = 50mA Cbyp = 100nFEnable6222 3.0V output noise010020030040050060070080090011010010001000010000Bypass Cap (pF)N o i s e (u V r m s )100uA 10mA 50mATurn on time, Vin = 3.0V, Iout =10mA, CBYP = 100nFTurn on time, Vin = 3.0V, Iout =50mA, CBYP = 100nFSP6222 3.0V Output Noise vs.CBYPAPPLICATION INFORMATION10100100010000100000100000010000000Frequency (Hz)SP6222 3.0Vout PSRR 10mA, 4.5Vin, Cbyp-10nFAPPLICATION INFORMATION639LQ9RXW7\SLFDO $SSOLFDWLRQ &LUFXLW IRU $GMXVWDEOH 2XWSXW9287 95() > 5 5 @10100100010000100000100000010000000PACKAGE: 5 PIN SC-70PACKAGE: 5 PIN SOT-23Sipex Corporation reserves the right to make changes to any products described herein.
