The BQ79758-Q1 provides high-accuracy cell voltage measurements for up to 18S battery modules in high-voltage battery management systems in xEV/EV. The monitor 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. This device has a state-of-the-art ADC architecture/measurement system meeting stringent automotive standard and safety requirements. With the daisy-chain isolated by transformer (or capacitor), the device is suitable for centralized or distributed architectures in xEV powertrain.
