とを特徴とするリセット信号発生回路。In a reset signal generation circuit that generates a reset signal by detecting a drop in circuit voltage due to a momentary interruption of the power supply voltage by comparing it with a reference voltage using a voltage comparator, the reference voltage of the voltage comparator is connected to the resistance of the circuit voltage. The voltage comparator is set by a voltage dividing circuit and a capacitor connected between the voltage dividing point and the ground terminal, and is configured to always apply a voltage higher than the circuit voltage to the voltage comparator as a driving voltage. Reset signal generation circuit.
