I have a project that requires a time delayed 12V DC supply. The "**broken link removed**" I found on ebay for $3 works perfectly - except for one problem......
When the 12V input to the circuit drops, I want the timing sequence to reset. It does reset if the 12v input is off for ~2 seconds - but if you drop and re-apply the 12v input too soon, the timing sequence doesn't reset. This won't work for my application. I need the timing sequence to reset immediately after the 12v input is off.
I hope I've described this accurately. I'm not very circuit savvy - so please respond appropriately (30 years of application development at IBM speaking here - but not much EE experience).
thanks in advance,
