STIB1060DM2T-L Does the IC have isolation for the microcontroller signals or should we add external optocouplers to protect it.

I am currently planning on build a low voltage 3 phase AC power supply for powering my DIY axial motor. I am scared if I input high voltage say 60V, it may have a chance of leak of current going to the micro-controller. I cant find any protection mentioned in the datasheet. I attached the circuit diagram.
