DESCRIPTION
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, a weak
pull-down of approximately 20uA is connected to the CHRG pin, indicating an “AC
present” condition.
Ground.
Charge Current Output. Provides charge current to the battery and regulates the final
float voltage to 4.2V.
Positive Input Supply Voltage. Provides power to the charger. VCC can range from 4.5V
to 6.0V and should be bypassed with at least a 1μF capacitor.
Open-Drain Charge Termination Status Output. When the battery is charging, the
CHRGT pin is pulled high by an external component such as an LED. After the charging
is completed, this pin is pulled low by internal N-channel MOSFET and it can be used as
a charging termination indicator.
Charge Current Program, Charge Current Monitor and Shutdown Pin.
