CHRG (Pin 1): Open-Drain Charge Status Output. When the battery is charging, the CHRG pin is pulled

low by an internal N-channel MOSFET. When the charge cycle is completed, high impedance is forced

to the CHRG pin and LD (pin 5) is pulled low, indicating an “AC present” condition.

GND (Pin 2): Ground.

BAT (Pin 3): Charge Current Output. It should be bypassed with at least a 1uF capacitor. It Provides

charge current to the battery and regulates the final float voltage to 4.2V. An internal precision resistor

divider from this pin sets the float voltage which is disconnected in shutdown mode.

VCC (Pin 4): Positive Input Supply Voltage. It Provides power to the charger VCC can range from 4.5V

LD (Pin 5): Open-Drain Charge Status Output. See CHRG pin (Pin 1).

PROG (Pin 6): Charge Current Program, Charge Current Monitor and Shutdown Pin. The charge

constant-current mode, this pin servos to 1V. In all modes, the voltage on this pin can be used to
