bq24745 Description

The bq24745 is a high-efficiency, synchronous battery charger with an integrated input-current parator, offering low ponent count for space-constrained, multi-chemistry battery-charging applications. The input-current, charge-current, and charge-voltage DACs allow very high regulation accuracies that can be easily programmed by the system power-management microcontroller using the SMBus interface. The bq24745...
