BQ24773RUYR Description

Short technical summary and product information.

The BQ24773RUYR from Texas Instruments is a multi-chemistry battery management IC designed for 1-4 series cell configurations. It supports Li-Ion, Li-Polymer, and Lithium Phosphate (LiFePO4) chemistries. The device integrates a switch-mode buck converter capable of delivering up to 8A charge current with programmable switching frequency from 600kHz to 1.2MHz. Input voltage range is 4.5V to 24V, with an absolute maximum of 30V.

 

Control is via an I2C interface, allowing precise regulation of charge voltage from 1.024V to 19.2V. The ultra-low quiescent current of 600µA enhances efficiency in portable applications. Operating temperature range is -40°C to 85°C, suitable for industrial environments.

 

Packaged in a 28-WQFN (4x4) or 28-WFQFN Exposed Pad, the IC is surface-mount compatible. It is RoHS3 compliant and has an MSL of 1 (unlimited). This device is ideal for battery charging in laptops, power tools, medical devices, and other multi-cell applications.
