N Channel MOSFETs need a high gate voltage to switch them on.

Great demonstration of Body diode. However, what's the implication of reverse biased MOSFET?
What an amazing walk through. Stoked for the rest. The above and beyond labeling and everything is great
Great explanation and totally practical
With the stacked mosfets, only one of the drains seems to be connected.
Thank you so much for your videos!
Concerning parallel semi conductors with NTCs (negative temperature coefficient).
They have to be thermal coupled. Isn't it?
Thus one of the parallel semi conductors having the highest temperature and thus is on its way to 'hell' is balanced by thermal coupling and heating the other ones as well. Thus forcing them to conduct more current and thus diminishing the own tendency of conducting more current by temperature rise.
Car engine management systems use the ground side switching more than high side switching Ground side switching is called "pull down" 12v switching (High) is called a pull up circuit. That applies to inputs and outputs
Hi Julian :
A couple of points : I think these days cars use a different wiring than the old everything to ground to prevent corrosion and connectivity issues .
The 4 x bank Mosfets could each be wired on a heat sink to balance thermal differences.
Thanks for video ,as always very clear .
Is n-channel the same thing as NPN?
OH MY GOD!!!! thank you for showing this, I've had the worst time trying to understand N-channel MOSFET's. you've made it so much clearer.
If I needed a 'normal' or regular pwm battery charger, would it be ok to have common positive? and just pulse the n-channel mosfet on the negative rail right?
