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. An internal programmable charge timer provides a backup safety feature for charge termination and is dynamically adjusted during the thermal regulation phase.The bq24085/6/7/8 automatically restarts the charge if the battery voltage falls below an internal threshold; sleep mode is set when the external input supply is removed.Multiple versions of this device family enable easy design of the bq24085/6/7/8 in cradle chargers or in the end equipment, while using low cost or high-end AC adapters.
Ideal for Low-Dropout Designs for Single-Cell Li-Ion or Li-Pol Packs in Space Limited Applications
Integrated Power FET and Current Sensor for up to 750-mA Charge Applications
