LOW VOLTAGE INHIBITING CIRCUIT FOR A MICROCOMPUTER

摘要

A low voltage inhibiting circuit for use with a microcomputer in which a reset signal is applied during power-up or whenever the voltage of an unregulated source to a regulated supply drops below a predetermined threshold level. The reset signal is removed whenever the voltage from the unregulated source is restored to a value which is above a second predetermined threshold value defined as being above the first threshold value 10 and after a predetermined period of time.
