Hey gurus,
Suppose I want to design a USB powered circuit (I actually do).
The circuit does XYZ (doesn't matter...some digital logic...caps...etc), it uses USB interface only as a power source (without data pins).
How should I properly protect the USB source from a short circuit ? (for example, due to some ceramic caps fail, bad design or even poor assembly [not intentionally of course...hehe] that eventually might lead to a short circuit)
USB interface - could be PC/laptop sourced...a short circuit might have a terrible and costly effect.
What's the best practice for this ? what's actually being implemented in the devices for those kind of failures ?
Thanks.
