ABSTRACT:
An improved power supply control circuit capable of restricting operation of a peripheral circuit before the level of voltage is stabilized and permitting the peripheral circuit to operate after the level of voltage is stabilized, which includes a level detecting unit having a plurality of serially connected transistors for decreasing the level of voltage applied to one side thereof in order; and a disenable signal generating unit, which has MOS transistors having a different channel and connected between voltage and the ground, for receiving a different level of voltage from the level detecting unit and for generating a certain disenable signal when the voltage reaches a certain level.
