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!
