I need to run a 3.3V logic line to a P-Channel MOSFET. Its running to the gate and I have 5V at the Source. I will be drawing .08mA when active... I'm not switching this on at any fast rate.
I am running this model is switchercad and noticing different MOSFET's giving different results... mainly when trying to turn the fet off with 3.3V some can some wont and I cant seem to find what is the determining factor.
I would then like to get some MOSFET's from digikey.
Example: I run my simulation with...
Fairchild: FQB11P06,FDC5614P works! FDS9933A,FDS4953 doesnt
I am not sure if it has to deal with the Rds(on), Qgate ????
Well... thanks for your input in advance.
