BQ24078RGTR TI Battery Charger IC | 16-VQFN (3x3) | 1A, Li-Ion, USB/AC

Product Overview

The BQ24078RGTR from Texas Instruments is a highly integrated, single-cell Li-Ion and Li-Pol battery charger IC designed for space-constrained portable applications. Housed in a compact 16-VQFN (3x3 mm) package, it supports up to 1A charge current from both USB and AC adapters. 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, ensuring instant system start-up even with a deeply discharged battery. Its low quiescent current and small footprint make it ideal for wearables, IoT devices, and medical equipment.
