USB EZ-PD™ Type-C Forum Discussions

I wanna build a Charge-Through VCONN Powered Device (CT-VPD).
I went throw the product catalog of infineon and other vendors and figured that the CCG2 is probably the right chip for my use case. I put a picture of my current PCB design as an attachment. I would appreciate your feedback on that design.

You can find some info on CT-VPDs from the USB-IF here, if you want to read up on the topic: https://www.usb.org/document-library/ctvpds-and-making-your-own-usb-cr-thingamajig

For a bit more context, my design is a USB keyboard attachment for a smartphone. The smartphone does support USB-PD 3.0 and can charge with more than 5.0V on VBUS. The CCG2 chip should enable the smartphone connected to the upstream port of my PCB, to power the keyboards micro controller via VCONN and still be charged with 5.0V or more over VBUS when a capable USB-PD charger is connected to the Charge-Through port of my PCB. You can see a good overview of the ports involved on page 10 of the PDF from the USB-IF. My keyboard PCB pretty much follows the same concept as the audio dongle that is shown there.

Because this setup is quite a new approach there is no application note in the datasheet of the CCG2 for it yet. Because of that I'm not sure how to properly design the PD circuitry. I was hoping that you could take a look at my design and give me some feedback if the design should work like that or if I need some adjustments.

I hope I can create a working design with the CCG2 chip or I would need to make a redesign with another vendor. I'm already looking for alternatives but the support engineers there are a bit slow to answer.

If you got any questions, just shoot them at me and I'll try to answer them.

Dear all,

I would like to communicate regarding the EZ-PD CCG8D (CYPD8225-97BZXI).

May I ask would you be available to communicate as well as update regarding the CYPD8225-97BZXI Altium Schematic as well as Footprint?

Please let me know.

Thank you.

Best regards,

Hello,

I have modified de EZ-PD CCGx Host SDK - CYPD3125-40LQXI-notebook project that come from the SDK because I am not using the same multiplexer that the one that is used on the EZ-PD CCG3 evaluation kit.  The project compile successfully.

I would like to include my own configuration table to that firmware instead of the one that is used by the EZ-PD CCG3 evaluation kit.

How can I add my own configuration table to the modified EZ-PD CCGx Host SDK - CYPD3125-40LQXI-notebook project?

Thank you

Best Regards,

Patrice

Hello, I'm recently start developing PD with CCG4(CYPD4225). I followed the getting started instruction and installed CCGX Host SDK 3.6. But there were only 2 CPD6228 project in the '/CCGX/Firmware/projects' folder. Where can I found the CCG4 projects ,'CYPD4226-40LQXI_notebook application' which was listed in the 'EZ-PD™ CCGx Host SDK user guide'? 

Best Regards.

For Sink only application,

Can i use one N-channel mosfet in consumer path, not B2B?

if can, how to connect VBUS_IN_NGDO / VBUS_IN_CTRL / VBUS_OUT_CTRL / VBUS_OUT_NGDO those pins to MOSFET?

Hi Infineon

When using 5V Legacy Charging, whether to detect the voltage division on the Type A to Type C CC signal line, and whether it complies with the ISNK_COARSE/ISNK_FINE setting.

for example 1

cc1 = 0.4V(limit 500mA)

ISNK_COARSE/ISNK_FINE setting = 2.25A

how about the CYPD3177 output?

for example 2

cc 1= 1.7V(limit 3A)

ISNK_COARSE/ISNK_FINE setting = 2.25A

how about the CYPD3177 output?

Hi,

In my design I am using CCG4 device, to program that device through I2C, can I use any USB-I2C Bridge converter or It will work only with INFINEON USB-I2C Bridge converter

Hi all , 

Do i have to have different  grounds at the input of the filter and it's output , or should I relate them and have only one ground  .

Hi,

What is the Test ID (TID) for CYPM1311-48LDXI,CYPD5225-96BZXI and CYPD5235-96BZXI?
