The BQ79712SB-Q1 and BQ79712PB-Q1 provide high-accuracy cell voltage measurements for 12S battery modules in high-voltage battery management systems in xEV/EV. The BQ797xx-Q1 family of monitors offers different channel options and supports high reuse of the established software and hardware across any platform. This device has advanced ADC architecture and measurement systems, meeting stringent automotive standards and safety requirements. With the daisy chain isolated by transformer (or capacitor), the device is designed for centralized or distributed architectures in xEV powertrain.
