What load you are driving?
I am driving a Bluetooth Low Energy chip.
Wawa:
There is always some small leak current when a fet is off, but you should have measured close to zero volt with the 47k resistor.
Did you take ESD precautions when handling/soldering (hot air) the fet.
Leo..
I always wear an ESD strap and carry the board around in anti-static bags. I believe I have taken ESD precautions when I handled the board.
MarkT:
Sounds like you blew the gate oxide handling the device - most MOSFETs are extremely static sensitive as they have no protection devices built in. Touching a MOSFET just by the gate pin when the other pins are
grounded is likely burn it out - the human body picks up dozens of volts of mains pickup which exceeds the
gate-source voltage spec. Keep MOSFETs in their anti-static packaging until they are safely in the circuit.
When I remove the 2.4 Ohm resistor, the P-FET works just fine. However, when I try to drive the load, it can only partially turn off. The whole thing has been really weird.
