BQ25150YFPR, IC BATT CHG LI-ION 1CELL 20DSBGA

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.
