TS12001
Version 1.3
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
(V
THRESH
),
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 V
THRESH
, the load switch is on-
active. When the input battery voltage falls to
V
THRESH
, the load switch is Off-Active™ and the
quiescent current draw is approximately 100pA.
FEATURES
Off-Active™ feature with ultra-low pico-amp
current
Best-in-class Off-active™ quiescent current of
100pA
Ultra-low on-active quiescent current of 70nA
Accurate on to Off-active™ voltage threshold
Threshold voltage options of 1.2V - 4.2V in
100mV steps (programmed at manufacturing)
Supervisory over-current limit shutdown
Low Rds(on): 175mΩ typical @ 5V
Low drop out disconnect from VBAT to loads
Turn-on slew rate controlled
500mV off to on-active hysteresis
APPLICATIONS
Portable Battery
Industrial
Medical
SmartCard
RFID
Energy Harvesting Systems

Note 1: 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 conditions” is not
implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
Note 2: All voltage values are with respect to network ground terminal.
Note 3: ESD testing is performed according to the respective JESD22 JEDEC standard.
