BQ2018SN-E1TR TI Battery Fuel Gauge | 8-SOIC | 1-Cell Li-Ion, I2C

Product Overview

The BQ2018SN-E1TR from Texas Instruments is a highly integrated battery fuel gauge IC designed for single-cell Li-Ion and Li-Polymer battery packs. It provides accurate state-of-charge (SOC) information using a patented algorithm that compensates for battery aging, temperature, and discharge rate. Housed in a compact 8-pin SOIC package, it communicates via I2C interface, making it ideal for portable and space-constrained applications.
