IRFZ44N is not working properly.its Vgs <1v. So how to make it completely on
I assume you refer to the top-side MOSFET and a possible problem with the boot-strapping circuit not generating enough gate drive to turn it on. For boot-strapping to work effectively you need to toggle the input pins of the IRS2110 at a fairly fast rate. If you are trying to put DC voltage levels on the input, the boot-strapping circuit will fail to operate correctly because it needs a reasonably fast toggle rate probably in the low kHz and above.

Boot-strapping is a diode clamp that generates a peak voltage higher than Vcc: -



Other than that the circuit detail looks correct apart from me nearly missing the tiny inverter you have on pin 12.
