I have the H Bridge circuit built and operating and installed, and when the current hits 50 amps, the relay(4pdt) opens the inputs and and all 4 Power FETs turn off, the relay is a small, low current, signal relay, and works well, but I was thinking to replace it with FETs. During normal operation, the disconnecting FETs (whether P or N) will see a Vgs of about 24or 12 volt, depending on if the power FET is on or off. I'm just wondering if the FETs can handle that much gate voltage. The gate voltage is taken to ground to turn the disconnecting FETs off.
