CE3102X 120mA Standalone Linear Li-Ion Battery Charger

CE3102X 120mA Standalone Linear Li-Ion Battery Charger

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, CHR.

Features

include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination.
