I am building a PCB that consists of a stepper motor driver (DRV8711) and had a confusion with the N-Channel MOSFET selection. I will power the driver through a 50V supply and the driver mentions typical gate drive voltage to be +10V higher than the supplied voltage. Which is the confusing part because I have never seen a MOSFET with max Vgs higher than it's max Vds. Is it constructed so that the short charging pulses don't damage the MOSFET?
In the official boost evaluation board TI also used a MOSFET with 20V Max Vgs while stating the board can be used with 24V which equals to around 34V gate voltage.
