How much current flows through a MOSFET when off?
given circuit this:
if mosfet off (ie. arduino pin low) current expect flow between drain , source? know "not much" talking maybe 10 na?
i asking because of low-power applications, if had (say) motor connected mosfet did not want drain battery while off (and might off while) can consider current through mosfet negligible?
i thinking of project: http://arduiniana.org/projects/the-reverse-geo-cache-puzzle/
he used polulo switch lets circuit turn off, wondering if going sleep (and having button connected reset) achieve same thing. control external devices, gps , motor, through mosfet or two.
(edit)
because above graphic linked number of pages has been amended have 150 ohm gate resistor (r1) rather 10 ohm 1 shown. mention subsequent comments on circuit make sense.

the datasheet tell think more that. looked @ couple , it's more 10ua 10na.
