BQ24079RGTR TI Battery Charger IC | 16-VQFN (3x3) | 1A, Li-Ion, USB/AC

Product Overview

The BQ24079RGTR is a highly integrated Li-Ion linear battery charger IC from Texas Instruments, designed for space-constrained portable applications. It operates from a USB port or AC adapter, supporting charge currents up to 1A. The device features dynamic power-path management (DPPM) that allows the system to be powered directly from the input while simultaneously charging the battery, enabling instant-on operation even with a deeply discharged battery. The 16-pin VQFN (3x3 mm) package makes it ideal for compact designs.
