BQ25015EVM 的说明
The bq25015EVM is a complete charger module for evaluating a single-chip charge solution using the bq25010/11/12/15/17 devices. It is designed to deliver up to 500 mA (bq25010/11/12) or 1000 mA (bq25015/17) of charge current to Li-Ion or Li-Pol applications.
The bq25010/11/12 has a highly integrated battery charge controller designed to work with external host commands. The charge current and other system parameters are programmable. An integrated synchronous buck converter (except the output inductor and capacitor) is incorporated in this chip as the supply from battery to system. For details, see the bq25010, bq25011, bq25012 Single-Chip Charger and DC/DC Converter IC for Bluetooth Headsets and Other Portable Applications data sheet (SLUS615) and bq25015, bq25017 Single-Chip Charger and DC/DC Converter IC for Portable Applications data sheet (SLUS721).
