Hello there I have a question if I implemente 45W car charger using Southchip SC8815 and it works fine and i'm thinking about using CYPD3171 instead of CYPD3175 to make it a powerbank dual role is there a change that should be done in hardware side ?
Or only in the firmware ?
I appreciate all your answer

Hii,
Since CYPD3171 and 3175, as well as Southchip's SC8915 and 8815, are pin to pin compatible you can configure it to work as a Power bank application.
The following changes has to be carried out:
1) For making it a DRP, you need to modify the hardware like adding consumer FET and checking the VBUS_IN_DISCHARGE connections.
2) And the firmware should be changed for the required application.
You can refer application diagram form the datasheet for additional details.
I hope this has answered your doubt.
