Hello Gabriel,

The OUT pin from the TPS2546 needs to be connected to VBUS on the Type-A connector. The IN pin will be connected to a system 5V. Everything else looks fine though. Let me know if this helps answer your question! If so, please click this resolved my issue

hello Adam

Thank you for your answer.

I have one more question.

The customer wants to use USB port of Cradle as OTG port.

Is there any problem in operation when it connect to a host device like PC?

Hello Gabriel,

Would you mind elaborating on how the customer intends to use the device as a OTG port?

Will you connected the device the TPS2546 is in to a charger or a port on a laptop?

Regards,
Adam
