ABSTRACT:
A starting circuit for an electronically controlled actuator having an integration capacitor provided in a control signal path and a power supply circuit for supplying a power supply voltage to the motor apparatus, comprises a comparator having first and second given voltages, and a switch circuit coupled to the comparator and to the integration capacitor. The comparator compares the power supply voltage with the first and second given voltages and provides a comparison result when the power supply voltage corresponds to a voltage range between the first and second given voltages. The switch circuit discharges the charge stored in the integration capacitor when the comparison result is provided from the comparator.
