For the first time ever, I needed a high side solenoid coil driver.
So reading up on high side drivers, I felt confident. P channel mosfet etc.
Does not work.
Come to find out that the source of a P channel mosfet is supposed to be
connected to the positive supply.
Source = source of elect
Found this:
What is the direction of current flow in P channel MOSFET?
[image: Simple MOSFET Switching Circuit – How to turn on / turn off N ...]
Current flows into the drain and out of the source. P-channel MOSFETs turn
on when the gate is a few volts below the source, and the drain-source
voltag
