bq7961x/bq7961x-Q1 Battery Monitors

Texas Instruments bq7961x/bq7961x-Q1 Battery Monitor, Balancer, and Protector provide high-accuracy cell voltage measurements in less than 200µs for 12S, 14S, and 16S battery modules in high-voltage battery management systems in HEV/EV. The family of monitors offers different channel options in the same package type, providing pin-to-pin compatibility and supporting high reuse of the established software and hardware across any platform. The integrated front-end filters enable the system to implement with simple, low voltage rating, differential RC filters on the cell input channels. The integrated, post-ADC, low-pass filters enable filtered, DC-like voltage measurements for a better state of charge (SOC) calculation. The Texas Instruments bq7961x/bq7961x-Q1 supports autonomous internal cell balancing with temperature monitoring to auto-pause and resumes balancing to avoid an over-temperature condition.
