BQ7721603PWR TI Battery Monitor | 24-TSSOP | 3-16S, OVP, UVP, OTP

Product Overview

The BQ7721603PWR from Texas Instruments is a high-performance battery monitor and protector IC designed for multi-cell Li-ion, Li-polymer, and LiFePO4 battery packs. It supports 3 to 16 series cells and provides accurate overvoltage (OVP), undervoltage (UVP), and overtemperature (OTP) protection. Housed in a compact 24-TSSOP package, it is ideal for space-constrained applications requiring robust battery management.
