bq24765 Description
The bq24765 is a high-efficiency, synchronous battery charger with two integrated 30-mΩ NMOS power MOSFETs, and an integrated input current parator, offering low ponent count for spaceconstraint, multi-chemistry battery charging applications. 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...
