Fuse is a vital protection device for many electronic devices. They simply monitor the current consumed by the circuit/load and in the event of unsafe current flowing through the circuit the fuse will blow itself and thus prevent the load/circuit form getting damaged by that high current. This type of fuse is called a mechanical fuse and there are many types of fuse such as fast blow, slow blow etc, but they suffer from one common draw back. When a fuse is blown it has to be replaced by the consumer/operator to make the device function normal again. This is the reason why many old electronic devices like toaster or electric kettle had a spare fuse provided along with the product.
To overcome this drawback, most of the modern electronic devices use an Electronic Fuse. An Electronic Fuse serves the same purpose of that of a mechanical fuse but it requires no replacement. It has a power electronic switch inside with closes and opens the circuit as required. In the unlikely event of a failure the switch is open the circuit and isolate it from the power supply, once the favorable condition returns the fuse can be reset by just clicking on a button. There is no hassle of purchasing a suitable value of fuse and replacing it for the old one. Interesting right?!! So, In this tutorial we will learn how to construct an Electronic Fuse circuit, how it works and how you could use one in your designs.
