BQ771602DPJR TI Battery Protection IC | 2-4S Li-Ion | Overvoltage Protection, 3.0V Threshold

Product Overview

The BQ771602DPJR is a secondary overvoltage protection IC for 2-series to 4-series Li-Ion battery packs from Texas Instruments. It provides a fixed overvoltage protection threshold of 3.0V per cell with a high accuracy of ±25mV. The device features a low quiescent current of 1µA (max) and a small package (WSON-8) making it ideal for space-constrained applications. It integrates a delay timer to prevent false triggering and can drive an external FET to disconnect the battery pack when an overvoltage condition is detected.
