blek Posted June 4, 2011 Report Share Posted June 4, 2011 i'm looking for a component that is normally closed, but when voltage/current is applied to the gate/trigger, it will:1) open the load (turn it off)2) keep it open while the current/voltage is applied to the gate at *around the same amount* of trigger current/voltage3) keep it open for a few milliseconds after the gate/trigger current/voltage drops lower than the holding threshold.4) after a that immediately closes the load again.i've read that the most reliable way to do this is with a depletion-mode mosfet, but (correct me if i'm wrong), hardly any of them has time delay in the milliseconds range.... so would adding a capacitor and resistor change it??:would it work even if there was no resistor (just the capacitor) Quote Link to comment Share on other sites More sharing options...
