BQ24753A

The BQ24753A is a high-efficiency, synchronous battery charger with integrated compensation and system power selector logic, offering low component count for space constrained Li-Ion and Li-Polymer 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 DAC or GPIOs.The BQ24753A charges two, three, or four series Li+ cells, supporting up to 10A of charge current, and is available in a 28-pin 5x5-mm thin VQFN package.
