BQ24074RGTT TI Battery Charger IC | 16-VQFN (3x3) | 1A, Li-Ion, USB/AC

Product Overview

The BQ24074RGTT is a highly integrated Li-Ion linear battery charger IC from Texas Instruments, designed for space-constrained portable applications. It operates from both USB and AC adapter inputs, 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 offers a compact solution for modern electronics.
