  • Publication number: 20240410944
    Abstract: An arrangement for testing the functionality of a semiconductor switch that is used as a fuse in a power supply line of a load in a motor vehicle electrical system. A voltage on the load side of the semiconductor switch or the current through the semiconductor switch can be detected. A controller is connected to the output and a monitoring component is connected to an input. The controller is configured to generate a signal which is applied to the output and via which the semiconductor switch can be switched off for a defined time interval in order to test the functionality, the time interval being so short that the functionality of the load is not impaired by this switching off. The monitoring component is configured to monitor the current applied to the input during the time interval or the voltage applied to the input during the time interval.
