W5500 Heating

Hello ,
I have used W5500 in one of my production hardware on site. Now this hardware is getting heating without any reason. I have tried same in my office and come to know that this hardware is heated even with supply. Can you suggest to avoid this heating.

W5x00 heats in any way, but it should NOT heat if you did not power it on.

If it does not communicate it does not mean chip not checking what is on the wire. So it functions and consumes power, unless you put PHY into power save mode.
