  I have to say... you have the neatest hand writing but you're a monster with the highlighter haha.

  Please note that eFuse also has a second, very different meaning in electronics: a One-Time Programmable memory bit integrated into the silicon die, for example you can permanently write protect or even read-protect the memory inside microcontrollers, game consoles like Xbox an PS have eFuse banks in the CPU to prevent firmware downgrade, etc.

  Watching this after accidentally reversing voltage and blowing up my buck converter along with some other electronics

  I didn’t even know this was available as a component!  Great Scott!

  The best protection for your circuit is when you accidentally soldered same-gendered connectors on both device and supply side. Can't smoke any electronic if you can't power it in the first place.

  The chip also has an ESD protection up to 2k volt, which is great.

  You have just solved a design problem I’ve been dealing with for almost a year!!!! Thanks you so much. I had no idea that these chips existed. Dang. I’m too old. Got my Electrical Engineering degree 46 years ago. Used a slide rule. No cell phones and no HP calculators. Oh, well. I will be using JLCPCB and building a new revision of my board with these efuses on them. Now to study the data sheet.<br><br>GREAT SCOTT is really great!! Thanks for a really great video!!

  I remember building one of these using a MOSFET and two transistors - It initially was meant to be a low-battery cut-off, but wound up having good short-circuit protection capabilities...

  i&apos;ve used circuits (with discrete components) that did OV/UV/OC protection over the years, but this is the first time I&apos;ve seen all that in ONE CHIP

  Great, maybe this is my next solution, working with colleagues capable of breaking anything they touch... <br><br>One thing I&apos;ve learned at work is: <i>Regardless of the amount of protection I put in my circuits, my (non-tech) colleagues will always find a way to destroy them...</i><br>They have:<br>- Put a powered PCB on top of a metal table, during testing...<br>- Ripped a USB-B port of my board, trough hole version... <br>- Reversed the polarity, on a prototype in which I told them to wait on me before powering it...<br>- Used the wrong adapter / battery / voltage...<br>- Used it outside without proper watertight enclosure...<br>- Put multiple PCB&apos;s on top of each-other, while powered...<br>- Peeled of a 0402 capacitor, because they thought it looked like a dirty breadcrumb...<br>- ... <br><br>I would dare the military to lend them one of their armored vehicles, for testing purposes. My colleagues would probably break it within the next 5 minutes, by just looking at it.
