Description
General part information
BQ24707 Series
The bq24707 and bq24707A devices are high-efficiency, synchronous battery chargers, offering low component count for space-constrained, multi-chemistry battery charging applications.
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 IC uses the internal input current register or external ILIM pin to throttle down PWM modulation to reduce the charge current.
