BQ771807DPJR TI Battery Protector | 8-WSON(3X4) | 2-4S Li-Ion, 3-25V

Product Overview

The BQ771807DPJR is a secondary overvoltage protection IC from Texas Instruments, designed for 2-series to 4-series Li-Ion battery packs. It features a precision overvoltage threshold of 4.35V per cell with ±1% accuracy, and a fixed overvoltage detection delay of 1 second. The device is available in a compact 8-pin WSON package (3mm x 4mm) and operates over a wide temperature range of -40°C to +110°C. It provides a low-power solution with typical supply current of 1µA in normal mode and 0.1µA in shutdown mode.
