STROEMFORSYNING PAA/AV-TILBAKESTILLINGSGENERATOR.

摘要

A power on/off reset generator (5) for monitoring a power supply (10) for a logic system powered from the monitored power supply. A precision-voltage sensor (20) produces a control signal for a time delay circuit (30) when the power supply rises above a preselected threshold voltage (ET). A delay signal is generated which maintains an active-LOW control signal to the logic system and causes a Schmitt trigger circuit (40) to produce a HIGH control signal to the logic system at the end of the delay signal.
