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.
APPLICATIONS
 Portable Battery
 Industrial
 Medical
 SmartCard
 RFID
 Energy Harvesting Systems
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
SUMMARY SPECIFICATIONS
 Wide input voltage range: 1.2V – 5.5V
 Packaged in a 8pin DFN (2x2)
