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. quote from: nick gammon on jun 26, 2013, 07:41 am if mosfet off (ie. arduino pin low) current expect flow between drain , source? know "not much" talking maybe 10 na? the datashe...
