TUSB4041I: µPD720115 replace inquiry

Part Number: TUSB4041I

Hi,

my customer is using µPD720115 + USB isolator + isolated power for USB to achieve four channel isolated USB.

It seems that  TUSB4041I  can beat uPD720115, right?

But we need 1.1V and 3.3V supply while uPD720115 can support single 5V supply.

What's our advantage?

Besides, do we have reference design of 4 channel isolated USB2.0?
