TS12001 nanoSmart Battery Management Under-Voltage Load Switch POWER PRODUCTS Description Features Off-Active feature with ultra-low pico-amp current The TS12001 Off-Active battery management load switch is Best-in-class Off-active quiescent current of 100pA used to protect a battery from excessive discharge. It consists Ultra-low on-active quiescent current of 70nA of an internally generated threshold voltage (VTHRESH), Accurate on to Off-active voltage threshold comparator with hysteresis, slew rate control for the load Threshold voltage options of 1.2V - 4.2V in 100mV steps switch, a P-Channel load switch, and an open-drain indicator (programmed at manufacturing) Supervisory over-current limit shutdown pin. When the input battery voltage is above VTHRESH, the Low Rds(on): 175m typical 5V load switch is on-active. When the input battery voltage falls Low drop out disconnect from VBAT to loads to VTHRESH, the load switch is Off-Active and the quiescent Turn-on slew rate controlled current draw is approximately 100pA. 500mV off to on-active hysteresis Applications Summary Wide input voltage range: 1.2V 5.5V Portable Battery Packaged in a 8pin DFN (2x2) Industrial Product is lead-free, Halogen Free, Medical RoHS / WEEE compliant SmartCard RFID Energy Harvesting Systems Block Diagram V CC V OU T R e g u la te d T h re s h o ld n PG G N D 1 of 11 TS12001 www.semtech.com Final Datasheet Rev 1.5 April 11, 2018 Semtech Typical Applications Disconnect the Battery Charger Load TS12001 VOUT VCC nPG C BYP GND Note: When the TS12001 is Off-Active, the battery will continue to charge through the body diode between VOUT and VCC.
