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.
The BQ24750 charges two, three, or four series Li+ cells, supporting up to 10 A of charge current, and is available in a 28-pin, 55-mm QFN package.
The BQ24750 controls external switches to prevent battery discharge back to the input, connect the adapter to the system, and to connect the battery to the system using 6-V Gate drives for better system efficiency. For maximum system safety, inrush-power limiting provides instantaneous response to high input voltage multiplied by current. This AC Over-Power protection (ACOP) feature limits the input-switch power to the programmed level on the ACOP pin, and Latches off if the high-power condition persists to prevent overheating.
The BQ24750 features Dynamic Power Management (DPM) and input power limiting. These features reduce battery charge current when the input power limit is reached to avoid overloading the AC adapter when supplying the load and the Battery Charger simultaneously. A highly-accurate current-sense Amplifier enables precise measurement of input current from the AC adapter to monitor the overall system power.
