BQ21061YFPT TI Battery Charger IC | 20-DSBGA | I2C, 1.5A Charge

Product Overview

The BQ21061YFPT from Texas Instruments is a highly integrated, I2C-controlled single-cell Li-Ion battery charger IC designed for space-constrained portable applications. Packaged in a compact 20-pin DSBGA (0.4mm pitch), it supports a wide input voltage range of 3.4V to 5.5V and delivers up to 1.5A charge current. The device integrates power path management, 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.
