Overview

The BQ76942EVM is Texas Instruments' evaluation module for the BQ76942 battery monitor and protector family. It is used to explore multi-cell lithium-ion and lithium-polymer pack monitoring, protection, and balancing functions in a lab setting. The board helps engineers validate pack-management hardware and firmware before moving to a custom design.

Why Choose This Part

This EVM gives engineers a practical reference platform for the BQ76942 battery monitor and protector, reducing risk during first hardware bring-up. It is useful when you need to validate cell-count scaling, protection thresholds, and balancing behavior on a real multi-cell pack. Using a vendor evaluation board also helps speed up firmware and system-level testing before committing to a custom BMS design.

Applications

Multi-cell lithium battery pack evaluation
Prototype and test 3-series to 10-series lithium-ion or lithium-polymer pack monitoring.
Battery protection development
Evaluate overvoltage, undervoltage, current, and temperature protection workflows for a pack design.
Cell balancing validation
Experiment with passive balancing behavior and balancing control strategies.
BMS firmware bring-up
Develop and debug host-side firmware that communicates with the battery monitor over a serial interface.
Pack characterization
Measure pack behavior during charge, discharge, and fault conditions in a controlled setup.

Getting Started

Use the TI EVM together with Texas Instruments' documentation for the BQ76942 device and the board-level guide. In practice, engineers typically connect the EVM to a host controller or TI support/software workflow, then verify pack wiring, cell-sense connections, and protection settings with a current-limited lab supply and a safe battery simulator or test pack. Start with low-risk bench validation before connecting a production battery.
