Abstract:
In order to solve a problem that during rise of an input voltage Vin, when the input voltage Vin exceeds a level of Vdetnull, but does not yet exceed a level of Vdetnull, no release signal is outputted, there is provided a voltage detecting circuit which is capable of removing a hysteresis voltage during the rise of the voltage Vin to output a release signal even in a case where the voltage Vin exceeds Vdetnull, but does not yet exceed Vdetnull.
