Abstract

PURPOSE: To surely detect the operation unstability of a semiconductor device which is liable to occur when the rise of source voltage is slow by providing a rise delay circuit of source voltage between a switch and the semiconductor device.
CONSTITUTION: A resistor 5 and a capacitor 6 are provided between a semiconductor device 1 and a switch 2. The delay time from the rise point of source voltage of the case when the switch 2 is closed may be set as desired by the product of the resistance 5 and the capacitor 6. It is equally well to provide the resistor 5 between the switch 2 and a DC electric power source 3.
