Hi Girish,
Sorry I was not clear. Based on your drawing the GH_A of the DRV8305 will be connected to the gate of the high side FET. It will not fully turn on the high side FET.
To fully turn on the high side FET requires the gate to source voltage of the high side to be approximately ~10V. The source should be 150V, so the gate should be ~160V. The DRV8305 cannot provide this voltage.
