Filed: 1987-02-10
Abstract: PURPOSE:To prevent malfunction of a device at leading/trailing by applying a signal while a prescribed time of delay is given and the device reaches a voltage capable of normal operation at the leading of the voltage and generating a reset signal interrupting the applied signal before the voltage reaches a voltage disabling the normal operation at the trailing of the voltage. CONSTITUTION:A 1st comparator 7 uses a 1st reference voltage to slice the DC voltage outputted from a DC power supply to form a rectangular waveform signal. The rectangular wave signal is subject to delay of the leading of the rectangular wave signal at the leading delay circuit 8 and given to a 2nd comparator 11. The 2nd comparator circuit 11 uses a 2nd reference voltage to slice an output signal of the leading delay circuit 8 thereby forming a reset signal whose leading is retarded for a prescribed time than the DC voltage. On the other hand, when the trailing voltage of the output signal of the leading delay circuit 8 reaches the 2nd reference voltage or below, the trailing discharge circuit 9 is operated, the trailing voltage is discharged rapidly into zero potential thereby forming the reset signal at the leading of the DC voltage. Thus, the malfunction of the device is prevented.
