There really is absolutely no connection between the power stage and control stage other than the control stage sending light across the void to the power stage (by LEDs inside the optocoupler) to tell it what to do. If something fails, the little beams of light to the power stage just don't do anything anymore. I don't think there's any possible way for the control board to be damaged by a naughty power stage.
