Product details

What the EMB1428QSQ/NOPB is and where it fits

The Texas Instruments EMB1428QSQ/NOPB is a battery balancer IC for Lithium Ion packs, handling 1 to 7 series cells over an SPI bus. 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.

Frequently asked questions

What is the EMB1428QSQ/NOPB used for?

It is a battery balancer for Lithium Ion packs of 1 to 7 series cells, typically used in automotive BMS, hybrid vehicle battery modules, and industrial energy storage where cell balancing improves cycle life and safety.

What is the equivalent or replacement for EMB1428QSQ/NOPB?

The BQ79612PAPRQ1 is a functional peer also AEC-Q100 qualified, but it is a battery monitor with SPI and UART, not a dedicated balancer. For a direct balancer replacement, stick with the EMB1428QSQ/NOPB.
