BQ25155YFPR TI Battery Charger IC | 20-DSBGA | 1-Cell Li-Ion, 500mA

Product Overview

The BQ25155YFPR from Texas Instruments is a highly integrated 1-cell Li-Ion battery charger IC designed for space-constrained portable applications. Housed in a compact 20-pin DSBGA package (2.0mm x 1.6mm), it supports charge currents up to 500mA and operates from an input voltage range of 3.4V to 5.5V. The device integrates a power path management system, allowing the system to be powered directly from the input while charging the battery. It also features programmable termination current, safety timers, and thermal regulation for reliable operation.
