Example implementations of the present disclosure relate to a vehicle, a fault monitoring device for a vehicle and a semiconductor device for detecting an overvoltage and/or an overcurrent. The semiconductor device includes a first die and a second die, which is configured to detect an overvoltage and/or an overcurrent in the electrical supply and/or communication of the first die. The semiconductor device also includes an output for outputting a signal, which indicates the overvoltage and/or the overcurrent.
