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.

Abstract: A receiver circuit receives an input voltage waveform from a single wire and generates an output bit stream. The receiver includes a voltage determination circuit which indicates whether a voltage level of the input voltage waveform has one of a high level that is higher than a high voltage threshold, a low level that is lower than a low voltage threshold, or a mid level that is between the high and low voltage levels. The receiver includes a bit value generator which provides a next bit value of the output bit stream as a first value when the voltage level is the high level, as a second value when the voltage level is the low level, and as a same value as an immediately previous bit value of the output bit stream when the voltage level is the mid level. The first and second values correspond to opposite logic states.
