BQ25100BYFPT TI Battery Charger IC | 6-DSBGA | 1-Cell Li-Ion, 250mA

Product Overview

The BQ25100BYFPT is a highly integrated 1-cell Li-Ion linear battery charger IC from Texas Instruments, designed for space-constrained portable applications. Housed in a compact 6-DSBGA package (0.9mm x 1.3mm), it offers a complete charging solution with minimal external components. The device supports charge currents up to 250mA and operates from a 4.2V to 6.5V input voltage range. It features a programmable charge current, pre-conditioning for deeply discharged batteries, and automatic charge termination. The BQ25100BYFPT is ideal for low-power devices such as wireless earbuds, wearable fitness trackers, and medical patches.
