nanoSmart® Battery Management
Under-Voltage Load Switch
Description
The TS12001 Off-Active⢠battery management load switch is
used to protect a battery from excessive discharge. It consists
of an internally generated threshold voltage (VTHRESH),
comparator with hysteresis, slew rate control for the load
switch, a P-Channel load switch, and an open-drain indicator
pin. When the input battery voltage is above VTHRESH, the
load switch is on-active. When the input battery voltage falls
to VTHRESH, the load switch is Off-Active⢠and the quiescent
current draw is approximately 100pA.
Summary Specifications
⢠Wide input voltage range: 1.2V â 5.5V
⢠Packaged in a 8pin DFN (2x2)
Applications
⢠Portable Battery
⢠Industrial
⢠Medical
⢠SmartCard
⢠RFID
⢠Energy Harvesting Systems
