ABSTRACT:
Circuit layout to control at least one electrical component of a motor vehicle via a control signal, wherein the circuit layout comprises a digital control unit that provides an output signal during its operation, the circuit layout has a supply terminal, and the digital control unit starts its operation when the supply terminal has an operating voltage above a predetermined threshold value. The digital control unit stops its operation when the supply terminal has an operating value below the threshold value, wherein the circuit layout comprises a circuit block in order to provide for the control signal, during the operation of the digital control unit the circuit block provides for the control signal based on the output signal of the digital control unit, and the circuit block maintains the momentary control signal for a predetermined period of time after the operation of the digital control unit is ended.
