BQ24251YFFR TI Battery Charger IC | 30-DSBGA | 1.5A, Li-Ion, USB/AC

Product Overview

The BQ24251YFFR from Texas Instruments is a highly integrated single-cell Li-Ion battery charger IC designed for space-constrained portable applications. Housed in a compact 30-ball DSBGA package (2.4mm x 2.4mm), it supports up to 1.5A charge current from both USB and AC adapter inputs. The device features dynamic power-path management (DPPM) that allows the system to be powered directly from the input while simultaneously charging the battery, ensuring instant system startup even with a deeply discharged battery. With integrated power FETs, reverse current protection, and I2C control, the BQ24251YFFR simplifies charger design and reduces external component count.
