This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...

There are many circuits for low voltage regulators. For higher voltages, such as supplies for valve circuits, the situation is different. That’s why we decided to design this simple regulator that can ...

Automotive applications need “smarter” drivers for their switches, which handle loads ranging from a fraction of an ampere to several amperes. Not only are these smart chips costly, but many times, ...

This circuit is suitable in every situation where over-current protection is required. Here we give an example from the model train world. Every seasoned model train enthusiast knows that there is ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.

What's the difference between a short-circuit current rating (SCCR) and an interrupting rating (IR)? If you're not sure, clearing up the confusion could be as simple as brushing up on your definitions ...
