BQ294711DSGR TI Battery Protection IC | 8-WSON (2x2) | 2-4S Li-Ion, Overvoltage Protection

Product Overview

The BQ294711DSGR from Texas Instruments is a secondary overvoltage protection IC designed for 2-series to 4-series Li-Ion and Li-Polymer battery packs. It provides a precise, programmable overvoltage threshold and a fixed overvoltage detection delay. The device is available in a compact 8-pin WSON (2x2 mm) package, making it ideal for space-constrained applications. It features a low power consumption of typically 1 µA in normal operation and 0.1 µA in shutdown mode. The BQ294711DSGR is part of the bq2947x family, which offers different overvoltage thresholds and delay options.
