can anybody suggest me what should be the Mosfet and mosfet driver if i want to design Stepper Motor Driver of 100V & more than 5A Stepper motor?

Hi Dhaval,
The absolute maximum voltage of the UCC27200/201 is 120VDC on the HS outputs. There is not much margin if you are using 100V nominal. It may work if you are careful to use voltage spike protection techniques, such as large bulk capacitance and surge suppression.
The UCC27201 has TTL inputs.
I am not aware of other high voltage FET drivers. The AC/DC and Isolated DC/DC forum may have other ideas.
