bq24753
Overview
The bq24753 is a high-efficiency, synchronous battery charger with integrated compensation and system power selector logic, offering low component count for space-constrained multi-chemistry battery charging applications. Ratiometric charge current and voltage programming allows for high regulation accuracies, and can be either hardwired with resistors or programmed by the system power-management microcontroller using a DAC or GPIOs. - Programmable Input Overvoltage Protection (OVP) - Dynamic Power Management (DPM) The bq24753 charges two, three, or four series Li+ cells, supporting up to 10 A of charge current, and is available in a 28-pin, 5x5-mm thin QFN package.
- 2 NMOS-NMOS Synchronous Buck Converter with 300 kHz Frequency and >95% Efficiency
