I am using the DRV8302 in a BLDC motor drive. I am looking to electronically switch off the power stage bus with a redundant mosfet to add fault tolerance. I would like to keep the DRV8302 powered while the power bus is turned off. Should I plan for a high side or low side switch? A low side switch would be simpler, but I am concerned about exceeding the max voltage rating between PGND and GND of +/-0.3V and max of +/-0.6V on the current amplifiers.
