BQ24751A Description

Short technical summary and product information.

The Texas Instruments BQ24751A is a versatile, host-controlled battery charger IC designed for multi-chemistry applications. It features a high-efficiency NMOS-NMOS synchronous buck converter operating at 300kHz, achieving over 95% efficiency.

 

This charger offers high-accuracy voltage and current regulation with ±0.5% charge voltage accuracy and ±3% charge current accuracy. It supports two, three, or four Li+ cells and can deliver up to 10A of charge current. The input operating range is from 5V to 24V AC/DC adapter.

 

Key features include automatic system power selection from AC/DC adapter or battery, programmable input overvoltage protection (OVP), and dynamic power management (DPM). The device supports ratiometric programming via resistors or DAC/GPIO host control for charge voltage and current. It is available in a compact 28-pin, 5x5-mm QFN package.

 

Applications for the BQ24751A include notebook computers, portable data capture terminals, portable printers, medical diagnostics equipment, battery bay chargers, and battery back-up systems.
