BQ7790509PWR TI Battery Protection IC | 20-TSSOP | 4-5S Li-Ion, OVP/UVP/OCP

Product Overview

The BQ7790509PWR from Texas Instruments is a highly integrated, secondary overvoltage protection IC designed for 4-series to 5-series Li-Ion and Li-Polymer battery packs. It provides accurate overvoltage, undervoltage, and overcurrent protection with a low quiescent current of typically 5 µA. Housed in a 20-pin TSSOP package, this device is ideal for power tools, e-bikes, and energy storage systems.
