BQ2031SN-A5TR TI Battery Charger IC | 16-SOIC | 2A, 4.1V/4.2V

Product Overview

The BQ2031SN-A5TR from Texas Instruments is a highly integrated, single-cell Li-Ion or Li-Polymer battery charger IC designed for space-constrained applications. It operates from a 4.5V to 6.5V input and provides up to 2A charge current with ±0.5% voltage accuracy. The device features a programmable charge current, charge voltage, and charge termination threshold. It includes a power path management function that allows the system to operate even when the battery is deeply discharged. The BQ2031SN-A5TR is available in a 16-pin SOIC package and is ideal for portable electronics, medical devices, and industrial equipment.
