Hi all
Yet another question about logic-level MOSFET circuits. As of now, my circuit is switching 40-ish V very fine,
but I was wondering if there is any reason why the same circuit shouldn't be able to switch a lower voltage,
like 5V or 12V...or maybe even 3V. Does it seem odd to use 5V to switch 5V? Well, I thought of doing it since
my USB controller has the usual 500mA USB limit.
So, using a logic level MOSFET to switch 5V? Go/no-go?
Thanks,
Nicholas
