BQ40Z80RSMT TI Battery Management IC | 32-VQFN (4x4) | 2-4 Series, Impedance Track

Product Overview

The BQ40Z80RSMT is a highly integrated, single-chip battery management solution from Texas Instruments, designed for 2-series to 4-series Li-ion and Li-polymer battery packs. It combines a precision analog front-end (AFE), a fuel gauge based on Impedance Track™ technology, and a secondary protection IC in a compact 32-pin VQFN (4x4 mm) package. The device provides accurate state-of-charge (SOC), state-of-health (SOH), and voltage/current/temperature monitoring, ensuring safe and efficient battery operation in demanding applications.
