Part Number: TPS2547

Hi,

TPS2547 is not supporting for Apple iPhone 11. We configured the TPS2547 as a CDP mode. All other manufactures its starts to charging except Apple Device.

What will be the issues, is that mode need to be changed...? Help me to solve this problem....

Regards,

Nishanth M

    Hello,

    It looks like you do not have the Dx_OUT pins connected to anything. Is this application a charging only system? i.e you will not have any data transmitted on the USB2.0 lines? If that is the case, then you can actually configure the TPS2547 to be in DCP_AUTO mode. This removes data capabilities of the system, but if you do not plan on having any data capabilities then DCP_AUTO would be the correct configuration.
