bq24753 Datasheet Host-controlled Multi-chemistry Battery Charger

Manufacturer: Texas Instruments

Overview: NOT REMENDED FOR NEW DESIGNS bq24753 .ti................................................................................................................................................

General Description

The bq24753 is a high-efficiency, synchronous battery charger with integrated pensation and system power selector logic, offering low ponent 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.
