I'm working on a battery powered circuit that is triggering an interrupt on an ic with an internal pull-up. The resistor value and normally closed switch can not be changed. The quiescent current is way too high for our application 200uA. Our target is 0-6uA.

Is there a FET/BJT circuit that could be added between the switch and the ic that could be designed to achieve the target current?

Any ideas? 
Thanks

\*\*I was using the NC switch to represent a physical characteristic of our device, now that I think about it it's more like a fuse. ie. We are trying to detect when the fuse is blown.
