I need some simple solution, for grounding an AdKey for a short time lets say 200ms, only once, on each power on.
I don´t know the exact needed time so it would be nice if i can change the time with an resistor or so. Till i found the right time.
I am using that circuit to power on/power off the load.
Is there a way to hold up the grounding from the on/off keypress a bit longer. becaus when i put the AdKey direct behind the on/off button. and u press the right time or make 2 short presses. It triggers. (The mcu take a bit time to bootup.)
So after 100ms or so the p-channel JFET(J1) should cuttoff,and stopping the ADKEY Ground. In a couple days my hfet should arrive and i can tell more.
Big Thanks in front.
