I was wondering if there are some particularly important mechanism by which one can break electronics, when undervolting it. Its pretty obvious that lots of electronics will not work properly if undervolted, but what about permanent damage? The question was motivated by repair work. I was wondering about what sorts of secondary effects one should look for when a damaged power supply was involved.
I imagine motors could be damaged if they stalled due to undervolting.
So what are specific mechanisms for permemenant damage due to undervolting (or better put undersupplying)? Are there even any?
To add to the question, what are components or simple circuits that fail when undersupplied?
