Description
PIN NAME
FUNCTION
CHRG GND BAT VCC
PROG
NC
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, CHRG is forced high impedance.When the CE3102X detects an undervoltage lockout condition, CHRG is forced high impedance.Ground Terminal.Charger Power Stage Output and Battery Voltage Sense Input.BAT pin provides charge current to the battery and regulates the final float voltage to 4.2V.A
