Patent ID: 6901326

Claim:
Circuit layout to control at least one electrical component of a motor vehicle via a control signal supplied to this component, wherein the circuit layout comprises a digital control unit that provides in its operation on an output of the digital control unit for an output signal for providing the control signal, the circuit layout has a supply terminal to set up an operating voltage that is provided by a power supply unit of the motor vehicle, the digital control unit is designed in a way that it starts its operation when an operating voltage above a predetermined threshold value occurs on the supply terminal and that it ends its operation when an operating voltage below the threshold value occurs on the supply terminal, the circuit layout comprises a circuit block connected with the output of the digital control unit in order to provide for the control signal, and the circuit block is designed in a way that it provides for the control signal based on the output signal of the digital control unit when the digital control unit is in operation and that it maintains the momentary control signal for a predetermined period of time when the operation of the digital control unit is ended.
