Multi-cell Synchronous Switch-mode Charger With System Power Selector

  The BQ24750 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 high regulation accuracies, and can be either hardwired with Resistors or programmed by the system power-management Microcontroller using a DAC or GPIOs.
