Hello All,
I"m a novice hardware engineer trying to think of a way to keep a keyboard up and running even when the trackball which is connected to it(they share the same power rails) shorts out.
Currently there is a filter which I could populate with a fuse but am unsure if this is a viable option. Respinning the PCB seems like over kill and I think there has got to be a more cost effective solution. Does anyone think a fuse is a good idea? So when the trackball shorts out the fuse pops and basically creates an open between the trackball +5V and the keyboard +5v.
If a fuse is an ok solution what should I be concerned about when picking the component?
Thanks for any replies!!
