BQ20Z655DBTR TI Battery Management IC | 2-4 Series Li-Ion, Impedance Track

Product Overview

The BQ20Z655DBTR is a highly integrated, single-chip battery management solution from Texas Instruments, designed for 2-4 series Li-Ion or Li-Polymer battery packs. It combines a gas gauge, protection, and authentication functions in a compact TSSOP-38 package. Utilizing TI's patented Impedance Track™ technology, it provides accurate state-of-charge (SOC) and state-of-health (SOH) monitoring over the battery's lifetime. The device supports SMBus v1.1 communication and includes integrated safety features such as overvoltage, undervoltage, overcurrent, short-circuit, and overtemperature protection.
