bq25150 Battery Charge Management IC

Texas Instruments bq25150 Battery Charge Management IC integrates the most common functions for wearable devices, such as a charger, an output voltage rail, ADC for battery and system monitoring, and a push-button controller. The bq25150 IC also integrates a linear charger that enables quick and accurate charging for small batteries. The device supports a charge current of up to 500mA and supports termination current down to 0.5mA for maximum charge. The battery is charged using a standard Li-Ion charge profile with three phases: pre-charge, constant current, and constant voltage regulation.
