BQ24041DSQR TI Battery Charger IC | 10-WSON (2x2) | 4.2V, 1A

Product Overview

The BQ24041DSQR from Texas Instruments is a highly integrated single-cell Li-Ion battery charger IC designed for space-constrained portable applications. It operates from a USB port or AC adapter and provides up to 1A charge current. The device features a 10-pin WSON package (2mm x 2mm) for minimal footprint. It includes power path management, allowing the system to be powered from the input source while simultaneously charging the battery. The charger supports pre-conditioning, constant current, and constant voltage charging with automatic termination. It also offers thermal regulation and protection against overvoltage, overcurrent, and reverse current.
