Claims

[Scope of utility model registration request]

In an electronic circuit that generates a reset signal when the power is turned on or when the power supply voltage drops, an integrator circuit of the power supply consisting of a resistor and a capacitor is connected to the reset output, and an N-gate thyristor whose anode is connected to the reset output is used. A reset circuit characterized in that a gate and a cathode of an N-gate thyristor are connected to the power source.
