Here is why MOSFET drivers are sometimes essential! || MOSFET Driver Part 1 (Driver, Bootstrapping)

In this video we will be having a closer look on how to drive MOSFETs. That means I will show you different examples on how to turn on/off a MOSFET with a microcontroller. We will investigate why and how much gate current is flowing and how the gate capacitance pretty much forces us to use a MOSFET driver at some point. Along the way you will also learn about what bootstrapping is and when to use it and you will hear a tiny bit about a gate-drive transformer. Let's get started!

If you made a full blown course of how to get started in constructing technology I’d pay for it. I love these videos would love to learn the basics so I could do projects like this.

The slowly blackening tip of the yellow highlighter gives me flashbacks to college.

[cornoadmin]

It bothers me that you always scrub the highlighter until it smears. Sorry, I couldn't hold it back any longer.

I am so glad so many people like yourself are out there, getting on youtube, and expanding their futures, while teaching. I'm an old fart, I've been working in this field more than fifty years, but you've taught me more than a thing or two, "surface mount, liquid solder, oven soldering", what's this world coming to? Very nice demonstration, thank you.

What can I say except give him an award.

Another reason to use MOSFET driver: cross-conduction prevention that could prevent your Metal Oxide Silicon Field Effect Transistor into becoming Magically Obliterated, Smoke n' Fire Emitting Transistor in a bridge configuration.

Dude you just resumed my B.S. Electrical Engineerging thesis on like 13 minutes.
WTF
Just awesome.

[sidewinderamm]

If you had 100 videos about driving MOSFET gates, I would probably binge what all of them today. This is great, thank you.

"The *field* of power electronics"
IC what you did there Scott :)

Edit: Damn, thread ended. Was hoping we'd see more electronics puns.

"But, of cousre, you don't know everything yet"
It's me, in every aspect of my life. Especially when I think I know what I'm doing.

[rohan_dr]

This is exactly what I was looking for. Really Great scott!!

[DrGreenGiant]

Genuinely the best explanation of MOSFETs and how to drive them I've ever seen. The only thing missing, which can trip people up, is depletion vs enhancement mode for both P and N channel

[nealmaxwell]

I have an exam on mosfets in two days. You have no idea how much this helped me

[Ritzz]

You know what, there is something therapeutic and calming about the way you speak. I've been subscribed for years and just had a moment.

[mattwillis]

Amazing work GreatScott!, this is yet another example of a series of your invaluable electronics learning resources.

[Bhavesh_g]

I started viewing your video nearly 4 years ago when I didnt knew anything about electronics and now I know things about electronics still I am enjoying how you explain

[scottmorgan]

I have no idea what you're talking about, but I do like your videos. Job well done...

[blanana_m]

Wonderful Video! I didn't know about mosfet drivers before this video but now I know what to do with them, Thanks!

[thomascornelissen]

Great timing on this subject. I was planning to look into the usage of gate drivers tomorrow.

[CTCTraining]

Huge thanks for including your workings in the videos ... so often folk try to cover such topics and just hand-wave the selection of component values. Big takeaway... if in doubt, add more MOSFETs!
