Hello
We have a product that has two usb ports and we are thinking to use two TPS2511. But what if we use only one control charger with two usb ports in parallel connected with data line + and -. What problems can we have if in usb ports we try to charge two phones in the same time, or else.

Thank you.

P.S
If we use two TPS2511, can we use one of them as a current limiter (for example 2.1A) and use this to divide the power into two usb ports ?
The reason for this current limiter is that our power supply has 3A and we need the 0.9A for other components so only 2.1A are for both usb ports. So the idea is to get fast charging but only when one usb port is busy.
