BQ25150YFPR, Battery Management I2C controlled 500-mA linear battery charger with Power Path, Low Iq, integrated LDO and 16-bit ADC 20-DSBG

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 push-button controller. The bq25150 IC also integrates a linear charger that enables quick and accurate charging for small batteries. The device supports charge current 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.
