Im trying to figure out the gate voltage to current ratio for this FET. I want to use it to make a digital version of daves Dummy load. This will be the first time I have ever used a FET, but i've done a lot of reading about how they work.
Anyways graph number 1, on characteristic is what I assume Im looking for. The problem is on its X and Y instead of saying like 2v, 10amps, it has like 10 to a power. Im sorry if this is really stupid bu I cant figure out how to interpret this thing and accurately figure out the gate voltage to drain current in the 1-5v region.
I need to figure out how much voltage to drive through the amp, to get 10 amps, I plan on using active cooling.
Also I have LM358s, the same as an lm324, only dual channel right? Then I have these on the way
http://ww1.microchip.com/downloads/en/DeviceDoc/21669D.pdfwill the microchip amps get a full 0 to source voltage rail to rail, unlike the lm358? Thats what im assuming by the description.
