Other Parts Discussed in Thread: TPS2543

 Hi Guys,

 Our customer is going to add common mode choke coil for TPS2543 D+/D- terminal.

But in case of this, the TPS2543 D+/D- are used for DCP charge mode confirming only.

Those signals are not used USB general communication.

 In this case, is a common mode choke coil needed?

 Of course, the customer uses ESD protection device for TPS2543 DP/DM. 

 Best regards,
