BQ2040SN-D111 TI Battery Fuel Gauge | 16-SOIC | 1-4 Cells, SBS 1.1

Product Overview

The BQ2040SN-D111 from Texas Instruments is a highly integrated battery fuel gauge IC designed for 1-4 series cell Li-Ion or Li-Polymer battery packs. It provides accurate state-of-charge (SOC) information using a patented VFC (Voltage-to-Frequency Conversion) algorithm. The device communicates via the SMBus (System Management Bus) v1.1 protocol, making it ideal for smart battery systems. Housed in a compact 16-SOIC package, it offers a cost-effective solution for portable electronics and industrial applications.
