BQ25120YFPR TI Battery Charger IC | 25-DSBGA | 500mA, 4.2V

Product Overview

The BQ25120YFPR from Texas Instruments is a highly integrated battery charge management IC designed for small-form-factor applications. It supports single-cell Li-Ion/Li-Pol batteries with a charge current up to 500 mA and a regulated voltage of 4.2 V. The device is housed in a compact 25-pin DSBGA package (2.0 mm × 2.0 mm), making it ideal for space-constrained designs. It integrates a power path management system, allowing the system to operate even with a deeply discharged battery.
