ABSTRACT:
A power on-off reset generator for monitoring a power supply for a logic system powered from the monitored power supply. A precision-voltage sensor produces a control signal for a time delay circuit when the power supply rises above a preselected value. A delay signal is generated which maintains an active-LOW control signal to the logic system and causes a Schmitt trigger circuit to produce a HIGH control signal to the logic system at the end of the delay signal.
