BSENSE (Pin 1): Battery Sense. This pin is used to Kelvin
sense the positive battery terminal and regulate the final
float voltage to 4.2V. An internal precision resistor divider
sets this float voltage and is disconnected in shutdown
mode. For Li-Ion applications, this pin must be electri-
cally connected to BAT .
BAT (Pin 2): Charge Current Output. Provides charge
current to the battery from the internal P-channel MOSFET.
CHRG (Pin 3): Charge Status Open-Drain Output. When

internal N-channel MOSFET. When the charge cycle is
completed, CHRG becomes high impedance.
GND (Pins 4, 9): Ground/Exposed Pad. The exposed
backside of the package (Pin 9) is also ground and must
be soldered to the PC board for maximum heat transfer.
PROG (Pin 5): Charge Current Program and Charge Cur-
rent Monitor. Charge current is programmed by connect-
ing a 1% resistor, R PROG , to ground. When charging in
constant-current mode, this pin servos to 1V. In all modes,
the battery is charging, the CHRG pin is pulled low by an
