I was wondering if anyone could help me out with this. I need to design a circuit that would somehow cut off a signal if there is a continuous +180V RMS hot short applied to it. The trick is that this signal cannot be altered and i can't use any components that would require power (i.e. opamps). Once the hot short is removed, the signal needs to function again, so you can't use fuses. I was thinking of somehow using FETs that would open if the gate voltage went above some level. Not sure how exactly to implement it thouhg.
Anyone have any idea?
Thanks a lot!
