description A multi-cell battery stack includes a microcontroller and a string of battery management and protection IC devices connected to one another in a daisy chain configuration. Each battery management and protection IC device can include a communication interface circuit includes pairs of differential input signal lines, receivers including respective current comparator circuits to receive differential signals on the differential input signal lines, and transmitters to provide outgoing differential signals on the differential input signal lines. A digital circuit block allows signals to pass between the receivers and transmitters.
