bq24725 Datasheet (Texas Instruments) - 2-4 Cell Li+ Battery SMBus Charge Controller

bq24725, 2-4 Cell Li+ Battery SMBus Charge Controller

The bq24725 is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, multi-chemistry battery charging applications.

The bq24725 uses two charge pumps to separately drive n-channel MOSFETs (ACFET, RBFET and BATFET) for automatic system power source selecti
