BQ25157YFPR TI Battery Charger IC | 20-DSBGA | 1A Charge, Power Path

Product Overview

The BQ25157YFPR is a highly integrated 1A linear battery charger IC from Texas Instruments, designed for single-cell Li-Ion and Li-Polymer batteries. It features power path management, allowing the system to be powered directly from the input source while charging the battery. The device is available in a compact 20-pin DSBGA package (YFP), making it ideal for space-constrained applications.
