Abstract: A vehicle communication network includes electronic control units arranged in a plurality of groups. The electronic control units pertaining to the same group are coupled to each other via a respective dedicated communication bus. A central controller is coupled to the plurality of local controllers. Electrical loads are coupled to one of the electronic control units. Each of the electronic control units is configured to decode the received CAN frame to produce the actuation signal for a respective electrical load in response to a CAN frame being received from the respective local controller and transmit a CAN wake-up frame to the respective local controller and encode the feedback signal into a CAN frame for transmission to the respective local controller in response to the feedback signal being received from the respective electrical load.

Abstract: An embodiment driver circuit comprises a power supply pin configured to receive a power supply voltage, and a set of control pins configured to provide a set of control signals for controlling switching of a set of switches of an h-bridge circuit comprising a pair of high-side switches and a pair of low-side switches. The driver circuit comprises control circuitry coupled to the control pins and configured to generate the control signals, and sensing circuitry coupled to the power supply pin and configured to generate a detection signal indicative of the power supply voltage exceeding a threshold value. The control circuitry is sensitive to the detection signal and is configured to generate the control signals to activate one of the pair of high-side switches and the pair of low-side switches and de-activate the other of the pair of high-side switches and the pair of low-side switches.
