A standard FET that needs 10V Gate drive would require +5V to -5V or +12V to +2V. | |

What it seems to me is that Logic Level would made sense if I wanted to switch the mosfet off with a voltage lower than the voltage in the Drain. Like: 12V in the drain, 0V would switch on, some positive voltage would switch off. In the case of 5V in the drain, and 5V or more to switch off, wouldn't a non logic level mosfet work? | |
