ABSTRACT:
An automatic reset circuit located on an integrated circuit chip, for providing automatically a reset signal to circuit elements which are required to be reset when a power supply is turned on. The reset circuit comprises a reset signal output means for providing a reset signal, a level detecting means for detecting that the electric potential of the power supply has reached a predetermined level, and a latching means for cutting off the reset signal according to the detecting output of the level detecting means. Once the latching means cuts off the reset signal, the latching means holds it so until the power supply voltage falls down to a certain level lower than the predetermined level.
