If you have an application in which a MOSFET is already used to switch a load, it is relatively easy to add short-circuit or overload protection. Here we make use of the internal resistance RDS(ON), ...

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” ...

Output short-circuit faults, overload conditions, other fault conditions, and high capacitance loads at startup can seriously strain or bring down an input supply, as well as damage the load. The ...
