Abstract:
A reset circuit for power removal from a control circuit controlling an application circuit which generates damaging electrical noise transients which can cause malfunction or destruction of the control circuit when a particular initiation event occurs, comprising:an input connected to a triggering signal from said application circuit indicative of onset of said initiation event; a power supply interrupting circuit for stopping a supply of power from a power supply to the control circuit of the application circuit when the signal indicating initiation of the event occurs at the input; and the interrupting circuit having a differentiator connecting the triggering signal to a delay circuit for continuing interruption of power to the control circuit for a desired time interval after the triggering signal has stopped to protect the control circuit from said damaging electrical noise transients which could still be present after the stoppage of the triggering signal.
