In this electronics basics episode we will have a closer look at eFuse ICs. They offer a ton of protection features for a very small price tag. That is why I will show you how I used such an eFuse in my LiPo Supercharger project and how you can use it for pretty much every electronics project. The included protection features are the following: undervoltage, overvoltage, reverse voltage, overcurrent and short circuit current. Let’s get started!

Very informative. I was using a power bank in a project and it would cut out all the time, after roughly a few seconds. I've also tried my very good Anker power bank and it behaved the same. So I've given up on that and just use a 2S lipo directly. I don't think I was drawing a huge amount of current.
I have so many ideas of circuits but so little knowledge in electronics. (barely kid level knowledge) It's hard to find some adult beginner oriented courses.
You are a great source of inspiration, great video's!
Danke schoen!

So.. you are telling me, the thing that prevents NintendoSwitch downgrades has other uses ?
I eFuse to believe it!
This audio needs to be de-essed
I totally thought this was going to be about the other kind of efuses (like in a micro controller). Was not expecting this, but I'm pleasantly surprised. Regarding the reverse voltage protection, what would be the down side of just rectifying the input with passive components?

Mmh, angry pixies…
Superb! Thank you.
They're very awesome indeed… unless you're a console hacker
Great video, but choose a more exciting example project than a blinking led
TPS259631 is even better: you can apply your own output voltage
I wanted to build your very old project (Bluetooth firework ignitor) but i can't find any schematics or parts list. Is it deleted or redirected on another page?
Next DIY billionair, congrats great scott!
does anyone know how "real" short circuit protection work? the one based on the voltage, not on the current
ughhh this video came like a week too late! after I spent 2 weeks to try and figure this out 😛 . thank you though!!
Will this circuit sell by elektor as kit?
A very usefull ic. Thanks!
Interesting. I wonder if there’s a 1.21 gigawatts model.
Thank you for this just what I needed
What happens to all your drawings you did over the years?
I wasn't able to find any eFuse that would work below 2.5V, it seems that the market is somewhere else than my circuits.
awesome as always
Awesome video with awesome concept. Thanks for the video !
Finally a pure electronics video is out! We love these videos keep making them…..thanks!
