BQ24031IRHLRQ1 TI Battery Charger IC | 20-VQFN (3.5X4.5) | 4.2V, 1A

Product Overview

The BQ24031IRHLRQ1 is a highly integrated Li-Ion linear charger and system power path management device from Texas Instruments. It operates from a USB port or AC adapter and supports charge currents up to 1A. The device features dynamic power path management (DPPM) that allows the system to be powered directly from the input source while simultaneously charging the battery. This ensures that the system can operate even with a deeply discharged battery. The BQ24031IRHLRQ1 is available in a compact 20-pin VQFN package (3.5mm x 4.5mm) and is qualified for automotive applications (AEC-Q100).
