Question - micro timer IC

[GH Crash]

I have an idea floating around in my head but everything depends upon finding a micro size timer chip. The timer just has to turn on/off a MOSFET. By micro, I mean a chip smaller than a postage stamp.

Does anyone know of a micro size low voltage IC timer? All I need is the part number of such a timer, or where to I might find out more information about micro timers.


Thanks for any help you can give.

Not to spoil the adventure aspect of this, but have you looked for small timers on eBay, Google's photos, etc.?

Or the kitchen gadgets aisle at MartMart? I have a bunch of little $0.99 kitchen timers in my lab, LCD and buttons, guts are probably your postage stamp size, one watch battery.

Strip it and connectorize the LCD and pushbuttons as a "programming fob", lose the piezo element (its drive might run you a photoMOS?) and you've Muntzed it good.

Like a sculptor who "chisels away everything that's not art". Sorta.
