Short circuit (over current) protection / full electronics / no relay

 Short circuit (over current) protection / full electronics / no relay

Short circuit (over current) protection / full electronics / no relay / you've never seen before

Hello, I am here with a new project which you haven't seen before (You can see it on other channels now, it will follow us constantly) The circuit is based on LM358 and TL431 TL431 is used as programmable zener. The LM358 amplifies the signal and allows the MOSFET to be active or passive. this way there is no need for a mechanical relay. The TL431 tuning process comes with a 50K pot. We have completed the system reset with one button, the system is sensitive, useful and open for development. Thanks for watching and don't forget to subscribe.

In this project I will show you how to create a simple circuit that can interrupt the current flow to a load when the adjusted current limit is reached. That means the circuit can act as an overcurrent or short circuit protection. Let's get started!

The video gives you all the information you need to recreate the protection circuit. In the next steps though I will give you some additional information.

Here you can find the schematic of the circuit along with pictures of my finished perfboard layout. Feel free to use them as a reference for your own circuit.
