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.

(2) Stresses beyond 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 beyond those indicated under “recommended operating con-
ditions” is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
(3) All voltage values are with respect to network ground terminal.
(4) ESD testing is performed according to the respective JESD22 JEDEC standard.
