It sits in the battery management system (BMS) of automotive and industrial equipment where cell balancing extends pack life and safety. Rated for -40°C to 125°C junction temperature, it's built for under-hood and high-temperature environments. The AEC-Q100 qualification means it meets automotive reliability standards for production programs. ## Cell count and chemistry — what fits your BOM The 1-7 cell range covers small to mid-size Li-ion stacks. The SPI interface lets a host MCU read cell voltages and trigger balancing without a separate ADC channel. ## Lifecycle and sourcing posture The EMB1428QSQ/NOPB is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect.","metaTitle":"EMB1428QSQ/NOPB Battery Balancer, Automotive AEC-Q100, SPI","metaDescription":"TI EMB1428QSQ/NOPB Li-ion battery balancer for 1-7 cells, SPI interface, -40°C to 125°C, 48-WQFN.
