Hi there. I need to design I circuit that when activated, by an input going from low to high (from zero to anything between 12V to 30V), will output iether high or low for approxomately 2 seconds.
This output will be powering a relay.
I need it to be as low a component count as possible and must be able to work upto 30V.
I originaly thaught about a nand gate monostable however the working voltages of CMOS put me off this, and, as mentioned it would be triggered from a posotive so a 555 monostable would be no good for this iether.
Thanks for any help, sorry for being vague.
