    One-Shot Circuit with Constant "Triggers"

    itsmoked, Your pointing out the non-retriggerable led me in the right direction, so I submitted your reply as a valuable post. Since I have never posted on here, I don't know what that does... but thanks again! Mike

    itsmoked, I did the further bit of experimenting I should have done before posting the question, and... I already have a timed circuit! Since the ignition does not shut off, the seat heater responds while the starter is turning. So, negative "remote starting" input, plus positive "starter...

    One-Shot Circuit with Constant "Triggers"

    itsmoked, Thank you for the help! I think I mis-stated my original post. It is not that the 555 "re"-triggers, but repeatedly triggers; it doesn't interrupt its own output, but just produces the timed output over and over again. I think this happens because the temperature chip provides its...

    One-Shot Circuit with Constant "Triggers"

    Hi, I am trying to design a temperature-controlled circuit for my vehicle and I can't figure out how to get a one-shot circuit from constant inputs... I have a remote starter which supplies a (-) output as long as the engine is running remotely. I also have a Maxim DS1620 IC which supplies a...
