BQ24725ARGRR Datasheet PDF - TI

The bq24725A is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, multi-chemistry battery charging applications.

●The bq24725A utilizes two charge pumps to separately drive n-channel MOSFETs (ACFET, RBFET and BATFET) for automatic system power source selection.

●SMBus controlled input current, charge current, and charge voltage DACs allow for very high regulation accuracies that can be easily programmed by the system power management micro-controller.

●The bq24725A uses internal input current register or external ILIM pin to throttle down PWM modulation to reduce the charge current.

●The bq24725A charges one, two, three or four series Li+ cells.
