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” ...

Short-circuit currents represent a tremendous amount of destructive energy, which can be released through electrical systems under fault conditions. Baseline short-circuit studies should be performed ...

Figure 1 This 4 to 18V-input, 12V-output SEPIC has short-circuit protection. Figure 2 The short-circuit input and output current for the circuit of Figure 1 differ at different voltages.

This simple circuit adds short-circuit load protection to a basic driver such as the output of a simple logic gate, while allowing it to control a high-power load operating at a much-higher voltage ...
