Name
Description
SOT23-5
1
STAT
Open-Drain Charge Status Output. When the battery is charging, the STAT pin is pulled low
by an internal N-channel MOSFET. When the charge cycle is completed, the pin is pulled
High.
2
GND
Ground.
3
BAT
Charge Current Output. Provides charge current to the battery and regulates the final float
voltage to 4.2V.
4
VIN
Positive Input Supply Voltage.
5
ISET
Charge Current Program and Charge Current Monitor Pin. The charge current is
programmed by connecting a 1% resistor, RISET, to ground. When charging in
constant-current mode, this pin servos to 1V. In all modes, the voltage on this pin can be
used to measure the charge current using the following formula: IBAT=1000/RISET
