I'd like to implement a safety mechanism in my circuit to avoid overvoltages/overcurrents in the event of a short, but am unsure as to what what the most robust or appropriate design approach would be. The primary rail is +15V and I want to limit the power to 15W.
After looking around, it seems that this should be pretty straightforward with discretes (e.g.link here), but would this be robust enough? Are there tricks/pitfalls in scaling as necessary?
I thought that there may be ICs for what I'd imagine is a common problem, but I'm unsure of what the appropriate one would be: inrush current limiter? surge suppression IC? power NTC thermistor? Something else entirely?
Or perhaps the simplest solution is a fuse, but that raises other questions as well. Will it trigger quickly enough? Does it need to be resettable?
Any help steering me in the right direction would be greatly appreciated.
