Brand new BQ24745 QFN-28
The bq24745 is a high-efficiency, synchronous battery charger with an integrated input-current comparator, offering low component 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 charges two, three, or four series Li+ cells, and is available in a 28-pin, 5 mm QFN package.
Features:
- NMOS-NMOS Synchronous Buck Converter with 300-kHz Frequency and >95% Efficiency
