BQ25100YFPR TI Battery Charger IC | 6-DSBGA | 250mA, Li-Ion

Product Overview

The BQ25100YFPR from Texas Instruments is a highly integrated, 250-mA linear battery charger for single-cell Li-Ion and Li-Polymer batteries. Housed in a compact 6-pin DSBGA package (0.9mm x 1.3mm), it is designed for space-constrained portable applications. The device operates from a 3.0V to 6.5V input and features a programmable charge current up to 250mA with ±10% accuracy. It includes a power path management system that allows the system to be powered from the input while charging the battery, and it supports a 1% accurate battery regulation voltage of 4.2V.
