I'm struggling with the design of a MOSFET based switch for high input voltages.
See schematic of the basic circuit that I've come up with:
When M3 would be ON, the voltage on it's drain would be approximately 0. This also means that M2 Vgs ~= (-50)V, exceeding the AMR for this MOSFET.
MOSFETs can't sustain this kind of high voltage on Vgs... What could be an appropriate solution for this?
