BQ24737 datasheet

Description

The BQ24737 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.
