I think what Robin is implying is that the fuse wont blow as fast as the driver could fry and that's certainly true for certain situations but if you short the motor wiring by dropping a screwdriver on it or the motor overheats and internally shorts a turn the fuse will still probably blow before the driver's MOSFET fails cos of thermal runaway unless it is very tightly spec'd...
