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.

120mA Standalone Linear Li-Ion Battery Charger CE3102X Series INTRODUCTION: The CE3102X is a complete, constant-current/ constant-voltage linear charger for single cell lithium-ion batteries. Its small size and ability to regulate low charge currents make the CE3102X especially well-suited for portable applications using low capacity rechargeable lithium-ion coin cells. Furthermore, the CE3102X is specifically designed to work within USB Power specifications. No external sense resistor i.
