Description

The bq24728 is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, multi-chemistry battery charging applications. The device uses 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 high regulation accuracies that can be programmed by the system power management micro-controller.

BQ24727 datasheet

Description

The BQ24727 is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, multi-chemistry battery charging applications. SMBus controlled input current, charge current, and charge voltage DACs allow for high regulation accuracies that can be programmed by the system power management micro-controller.

The device uses 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 digital-to-analog converters (DACs) allow for very high-regulation accuracies that can be easily programmed by the system power management microcontroller.
