Description (continued)

The inclusion of the isolated, bidirectional, daisy chain ports supports both capacitor- and transformer-based isolation, allowing the use of the most effective components for centralized or distribution architectures commonly found in the xEV powertrain system. This device also includes eight GPIOs or auxiliary inputs that can be used for external thermistor measurements.

Host communication to the BQ7961x-Q1 family of devices can be connected via the device's dedicated UART interface or through a communication bridge device, BQ79600. Additionally, an isolated, differential daisy-chain communication interface allows the host to communicate with the entire battery stack over a single interface. in the event of a communication line break, the daisy-chain communication interface is configurable to a ring architecture that allows the host to talk to devices at either end of the stack.
