Patent attributes
A Controller Area Network, CAN, transceiver comprising a receiver arrangement for coupling to a CAN bus and configured to determine a differential signal from analog signalling received from the CAN bus; and a receive output for coupling to a CAN controller and wherein the receiver arrangement provides a digital output signal to the receive output based on the differential signal; wherein the receiver arrangement operates in at least a first mode in which it is configured to provide the digital output signal comprising logic 0 when the differential signal is greater than a first receiver threshold and provide the digital output signal comprising logic 1 when the differential signal is less than said first receiver threshold unless said differential signal satisfies a condition, whereupon the receiver arrangement is configured to provide the digital output signal comprising logic 0, wherein the condition comprises the differential signal being below an activity-voltage threshold.
