Hi All
I am working on a circuit with multiple mosfets connected in weird and wonderful ways.
My knowledge on floating voltages only goes so far.
Could there ever be a case where a floating voltage causes damage to a part by floating up/down to a voltage which is outside the spec of the part?
e.g. drain of mosfet connected to GND, floating source floats to voltage above the parts max source drain voltage?
I am thinking about the floating source voltage being affected by environmental EMI.
Probably a silly question, forgive my ignorance!
Any thoughts would be much appreciated
