Abstract: A circuit arrangement for detecting a glitch on a supply voltage comprising a low pass filter arrangement coupled to a supply terminal and configured provide a filtered supply voltage. The circuit arrangement comprises a first and second detector circuit each configured to receive the supply voltage and the filtered supply voltage and configured to provide a first and second detection signal indicative of a glitch comprising a transient, positive and a transient negative change in the supply voltage at a first detector output terminal and second detector output terminal respectively. The circuit arrangement further comprises a circuit-arrangement output terminal configured to provide an output signal indicative of the detection of a glitch in the supply voltage based on the first detection signal and the second detection signal.

Abstract: The disclosure relates to a transceiver device, an electronic control unit and an associated method. The transceiver device is suitable for communicating between one or more network protocol controllers and a network bus and comprises: first interface circuitry configured to communicate with the one or more network protocol controllers; second interface circuitry configured to communicate with the one or more network protocol controllers; and selector circuitry configured to switch communication with the one or more network protocol controllers from the first interface circuitry to the second interface circuitry in response to a communication error in data carried on the first interface circuitry.
