ISO808 Ground connection

[sabari1]

in ISO808 I have connected +5V at VDD and +28V at VCC. In my application isolation is not required so is it ok if I short GNDDD and GNDCC with filter?

Well, you can certainly connect the two GND.
However, the question then arises as to why you would want to pay a significantly higher price for the then unused insulation than, for example, with the cheaper IPS8160HQ or IPS8160HQ-1?

Thank you Peter for your suggestion, In our application we need OUT_EN pin and I have gone through the datasheet of IPS8160HQ Ic but there is no such kind of OUT_EN pin. Could you suggest me any High side driver IC with the function of 8 channel, over current protection, thermal shut down , fault detection and Out_EN?

For example, you could use the VNI8200XP, which has OUT_EN but can only be used via SPI because OUT_EN is shared with IN3. Otherwise, you can stay with the ISO808.
