ABSOLUTE MAXIMUM RATINGS
Supply Voltage (VIN)....................................................................................... -0.3V to 7V
Input Signals (SHDN, EN,CMP) ...................................................................... -0.3V to 7V
Battery Charging Current (IBAT)....................................................................................1.2A
Operating Junction Temperature................................................................... -40C to 150°C
Storage Temperature Range.........................................................................-65°C to 150°C
RoHS / Pb-free Peak Package Solder Reflow Temp(40 seconds max. exposure) ............260°C (+0 -5)
Note: Exceeding these ratings could cause damage to the device. All voltages are with respect to
Ground. Currents are positive into, negative out of specified terminal.

FUNCTIONAL PIN DESCRIPTION
Description
Charging Output - This pin is wired to the positive terminal of the battery. (The negative battery terminal is wired
to GND.)
Charge Current Programming Pin - A resistor (Rccp) is connected between this pin and GND. See application
section for programming information.
Compensation Pin – Apply a 0.01µF capacitor between CMP and VIN pins.
Charge Termination Programming Pin – A resistor (Rctp) is connected between this pin and GND See
application section for programming information.
Enable - Applying a TTL compatible Hi signal enables the charger, a Low signal disables the charger and puts it
in sleep mode.
Common Ground.
Status - This pin is a logic low level when the battery is being charged. Pin can sink up to 5mA.
Voltage Input – Supply Voltage. Must be greater than VBAT to charge.
