Abstract
A reset generator circuit including a power monitor subcircuit which provides first and second logic level signals which specify the power supply as being above or below a preselected threshold level. A logic circuit comprising a series of interconnected NAND gates responds to the output signals generated by the power monitor subcircuit and to a signal from a capacitor charge monitor circuit. The capacitor charge monitor circuit develops logic signals which reflect the magnitude of the voltage across a capacitor which is part of a timing circuit. The control signal output from the logic circuit drives one input to a reset control gate and also controls the charge on the capacitor. The other input to the reset gate is also driven by the charge monitor circuit. The reset gate operates a switching element which provides the proper reset signal adapted for coupling to a microprocessor.
