BQ24060 具有热稳压器的 1A 单片锂离子和锂聚合物充电管理 IC
BQ24060 描述
The bq2406x series are highly integrated Li-Ion and Li-Pol linear chargers, targeted at space-limited portable applications. The bq2406x 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. An internal programmable charge timer provides a backup safety feature for charge termination and is dynamically adjusted during the thermal regulation phase. The bq2406x automatically re-starts the charge if the battery voltage falls below an internal threshold; sleep mode is set when the external input supply is removed.
