ITERM (Pin 1): Charge Termination Program. The charge
termination current threshold current is programmed by
connecting a 1% resistor, R TERM , to ground. The current
threshold I TERM , is set by the following formula:
100 V 100 V
I TERM = , R TERM =
R TERM I TERM
BAT (Pin 2): Charge Current Output. Provides charge
current to the battery from the internal P-channel MOSFET,
and regulates the final float voltage to 4.2V. An internal
precision resistor divider from this pin sets the float

voltage. This divider is disconnected in shutdown mode to
minimize current drain from the battery.
CHRG (Pin 3): Charge Status Open-Drain Output. When
the battery is charging, the CHRG pin is pulled low by an
internal N-channel MOSFET. When the charge cycle is
completed, CHRG becomes high impedance.
GND (Pins 4, 9): Ground/Exposed Pad. The exposed
backside package pad (Pin 9) is electrical ground and
must be soldered to the PC board for maximum heat
transfer.
