BQ24075EVM

评估板, BQ24075 1.5A USB易用锂离子电池充电器, 电源路径管理集成电路

The is an evaluation module for BQ24075, an integrated Li ion linear charger and system power path management device targeted at space limited portable applications. The devices operate from either a USB port or AC adapter and support charge currents up to 1.5A. The evaluation module also supports bq24072/3/4/9 and bq24230/2 bqTiny-III devices. The charger is programmed from the factory to deliver 0.9A of charging current. This evaluation module was designed as a stand alone evaluation module, but it also can be interfaced with the system and host via the connectors and headers.
