BQ24271YFFR TI Battery Charger IC | 49-DSBGA (2.8X2.8) | I2C, 1.5A

Product Overview

The BQ24271YFFR is a highly integrated single-cell Li-Ion battery charger from Texas Instruments, designed for space-constrained portable applications. It features a 1.5A charge current with I2C programmable settings, supporting USB and adapter input. The device operates from a 3.9V to 6.2V input voltage range and includes power path management, allowing the system to run even with a deeply discharged battery. Housed in a compact 49-DSBGA (2.8x2.8mm) package, it is ideal for wearables, smartphones, and IoT devices.
