BQ7720702DSSR TI Battery Monitor | 12-WSON (3x2) | 1-4S, 3.6V Threshold

Product Overview

The BQ7720702DSSR is a high-precision battery monitor and protector from Texas Instruments, designed for 1- to 4-series Li-ion, Li-Polymer, and LiFePO4 battery packs. It integrates overvoltage, undervoltage, and open-wire detection with a fixed threshold of 3.6 V for overvoltage protection. Housed in a compact 12-WSON (3x2 mm) package, it offers a low quiescent current of 1 µA (typical) in normal operation and 0.1 µA in shutdown mode, making it ideal for portable and standby applications.
