VEHICLE CIRCUIT ASSEMBLY FOR SUPPLYING AN ELECTRIC LOAD WITH A VEHICLE ON-BOARD VOLTAGE IN ORDER TO DETECT AN OVERLOAD

The invention relates to a vehicle circuit assembly (1) for supplying an electric load (2) with a vehicle on-board voltage (UFB) in order to detect an overload, said electric load (2) having a specifiable nominal power. The vehicle circuit assembly comprises: - a vehicle on-board voltage input (E1) and - a controller (3) for controlling a vehicle function, wherein the controller (3) has an integrated semiconductor component (3a), for example a system basis chip (SBC), and the integrated semiconductor component has an integrated high-side switch (S1) which is connected to the vehicle on-board voltage input (E1) in order to switch a vehicle on-board voltage (UFB) being applied to the vehicle on-board voltage input (E1) to a high-side switch output (A1). The high-side switch output (A1) has a specified current-carrying capacity, and the controller (3) is designed to detect the output current (IA1) of the high-side switch output (A1), the nominal power consumption of the nominal power to be provided lying above the specified current-carrying capacity of the high-side switch output (A1).
