BQ7720705DSSR TI Battery Protection IC | 12-WSON (3x2) | 2-7S, OVP/OCP

Product Overview

The BQ7720705DSSR is a high-performance battery protection IC from Texas Instruments, designed for 2-series to 7-series Li-ion, Li-polymer, and LiFePO4 battery packs. It integrates overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP), short-circuit protection (SCP), and open-wire detection. Housed in a compact 12-pin WSON (3x2 mm) package, it offers a low quiescent current of 1 µA (typical) and supports a wide operating temperature range of -40°C to +85°C. This device is ideal for applications requiring high accuracy and reliability, such as power tools, e-bikes, and energy storage systems.
