I have a -15V - 0V(Gnd) - +15V power source that I have to connect to a PCB while ensuring that if any two of these, or all three are connected wrong still there is no damage to the PCB. Is there practically viable way to do this. I know implementing a reverse polarity protection of a +15V - 0V (Gnd) is straight forward and I have done that many times, with diodes and P-channel FETs.
Have spend a couple of days on this and haven't been able to come up with any way to do this.
TIA,
Richa.
