BQ24085DRCR Datasheet PDF - TI

●DESCRIPTION

●The bq24085/6/7/8 series are highly integrated Li-Ion and Li-Pol linear chargers, targeted at space-limited portable applications. The bq24085/6/7/8 series offers a variety of safety features and functional options, while still implementing a complete charging system in a small package. The battery is charged in three phases: conditioning, constant or thermally regulated current, and constant voltage. Charge is terminated based on minimum current.
