BQ24086EVM-Battery Charger Evaluation Module

The bq24085/6/7 evaluation module (EVM) provides a convenient method for evaluating the performance of a charge management solution for portable applications using the bq24085/6/7 product family. The charger is designed to deliver up to 750 mA of continuous charge current for single-cell Li-Ion or Li-polymer applications using a DC power supply. The bq24085/6/7 series are highly integrated Li-Ion and Li-polymer linear chargers, targeted at space-limited portable applications. The bq24085/6/7 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 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. Multiple versions of this device family enable easy design of the bq24085/6/7 in cradle chargers or in the end equipment, while using low-cost or high-end AC adapters.
