How can I make my car fly? Put it in an airplane.

You can provide an isolated power supply and opto-coupled input to the driver. Possible, but not reasonable for simple applications. Specialized high-side drivers with bootstrap power supply are commonly used, but they have limitations.

ya i m using isolator circuit for the power and control signals..... but i m not sure that can i use this for high side mosfet or not

The "low side" device specification refers to common ground for logic input and source node. With individually isolated supply and control, it can be used for high-side as well. Of course, the DC/DC and logic isolator's dielectric strength must be sufficient and the logic isolator should have suitable common mode rejection for fast transients.

u have any data from where i read all other things

Not particularly. Various manufacturer datasheets and own design considerations.
