Texas Instruments BQ24088EVM
The bq24085/6/7/8 evaluation module (EVM) provides a convenient method for evaluating the performance of a charge management solution for portable applications using the bq24085/6/7/8 product family. The charger is designed to deliver up to 750 mA of continuous chargecurrent for single-cell Li-Ion or Li-polymer applications using a DC power supply.The bq24085/6/7/8 series are highly integrated Li-Ion and Li-polymer 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 abackup safety feature for charge termination and is dynamically adjusted during the thermal regulation phase. The bq24085/6/7/8 automatically re-starts the charge if the battery voltage falls below an internalthreshold; 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.
