Hi everyone,
I am using this MOSFET IRF5305 and I'm afraid I don't quite understand how this device works. I am following an application note by Microchip called AN857:
ww1.microchip.com/downloads/en/appnotes/00857a.pdf
The other MOSFET in the circuit IRLI3705 I understand. I give the gate a voltage (12V) and the drain to source conducts current. When I don't give it a voltage then it does not.
The IRF5305 MOSFET however, despite the fact that I give the gate voltage or not, it seems to conduct. Now I notice that the voltage drops down to 11.62 volts when I do the switch between applying 12V to the gate, and applying ground to the gate. Can you clarify this to me. I do not understand this MOSFET at all.
