USB EZ-PD™ Type-C Forum Discussions

Hello, I have programmed CCG3 for CTD( charge through dongle application). I have CCG2 in the design and I succesfully programmed with the latest CTD dongle and I am getting PD negotiation 20V successfully from USB C power adapter to the CCG3 USB C port. However, the laptop won't charge/ is not indicating a charger is plugged in which seems like a CCG3 issue.

I am not sure I have the latest CCG3 FW image since I only programmed over USB what was given in the EZ PD configuration utility. @Pranava_YN maybe you can help since you provided CCG2 CTD image? I need CCG3 CTD image that can be programmed with EZ PD configuration utility, I have only used Tools-configure device so far, I have not done Tools->update Firmware.

The image CCG3 is programmed with  is version 3.0.2.903 for both bootloader and firmware 1 for base version. if this is the latest maybe there is some other HW issue or other issue

Dear Team

I will design the Power bank + 15W wireless charger.

So I need a real schematic of REF_10WTX_QI_4102.

Please share with me the REF_10WTX_QI_4102 demo board schematic.

Hello My Name is yoonju! 

I have some Question about CYPD5225-96BZXI + TigerLake-H Configuration.

We are implementing Type-C (DP/USB3) I/F using CYPD5225-96BZXI on TigerLake-H Platform.

The important points are as follows.

1. We do not implementing Thunderbolt 4 I/F, Only USB3.1 & DP in TYPE-C 1 Port.

2. We do not Implementing Retimer I/F, Only Direct Connected Type-C Port About USB3.1 & DP Signal.

3. And we do not using  Battery Charger I/F & Embedded Controller(EC)

** Please refer to the attached block diagram.

<Question>

1. Basically, for TigerLake-H, is there a .hex file of the supplied CYPD5225-96BZXI?

2. In the case of the above configuration, do I have to modify the .hex file provided by default a lot?

3. Where can I find documentation about the compilation and download environment?

I would be very grateful if you could give me an answer.

Dear Support Team,

we are upgrading our product with a dual charger functionality 1xUSB-A and 1xUSB-C. It is a power source only application supplied by 12V batteries. Your controller product line CCG3PA seems to be a good fit for our needs and therefore I'd like to kindly ask for your technical support. The target of our application is to support the same features, protocols and voltage/current levels as the EVM CY4532 listed in the KIT guide in table 3-2 and 3-3. We had a few more questions about the implementation, would you be so kind to help out, please!

1. Please find the block diagram attached: two I2C bus is connected to CCG3PA, in case of I2C_0, the devices acts as master controlling the DC/DC converters, while on the other bus I2C_1, the CCG3PA is a slave device communicating with the MCU. Is it possible to control both buck-boost via same I2C interface?

2. Are there any constraints on setting the I2C addresses of the CCG3PA?

3. In case of the PFET(s) block for USB-C: is it OK to use a single MOSFET or it is necessary to implement (double) back-to-back MOSFETs for bi-directional switch-off?

4. Are there any constraint on setting the default output voltage of the buck-boost supplies?

5. Do you see any issues regarding the feasibility of our concept shown in the block diagram? Any comments are welcome and appreciated!

6. Can you share with us the schematic diagram of the design https://www.infineon.com/cms/en/product/evaluation-boards/vd_usb_cg3pa_39w_car/ ? As far as I could check, the design files available online belong to a totally different application.

Thanks a lot and best regards,
Adam

Hi!

In our docking station we have support for 100W / 5A power source and the Source PDO has 5000mA configured.  Originally, we had the Port Role configured as Source and later Dual Port + Default Port Role = Source. When we had like this, the system exposed 20V / 5A PDO to the laptops so they charged with 100W when supported. 

However, we noticed that some laptops didnt initiate DP-alt mode and/or USB-communication 100% of the time and if we changed to Dual Role, Default port role = Sink so that dock initially sink 5V and then we trigger a PR_Swap to initiate 20V charging we got much better compatibility with tricky laptops.

But, problem is that the PDO that is communicated to the laptop after this PR_Swap is made, only max current 3A is added in the response with the result that some laptops (e.g. Macbooks) will not move up to 5A charging. Looks like the 5A support is somehow "filtered" out?

How do we solve this? Have attached Analyzer dump and config-file.

Cheers

Hi,

What is the most appropriate function to use in the CCP3PA firmware to stop an active charging session? The application is a PD power source. We are putting in conditions (if/else) and if the condition is met, we would like to the CCP3PA source to stop providing power to the sink (without physically unplugging the cable).

Thanks,
Jonathan

I have a charge through dongle design and I'm trying to program a CCG2 from a CCG3 ( CCG3 device programmed successfully) .

When I connect I2C-INT from CCG3 to CCG2 the CCG3 can't connect to USB Billboard ( I2C-int is low even with 2.2K pullup to 3.3V).

When I disconnect I2C-INT( CCG3 billboard connects) and just connect I2C-SCL and I2C-SDA from CCG3 to CCG2, I see the CCG2 IC but i'm getting a programming error ( device still in bootloader mode) I'm trying to program the application firmware. Any ideas how to get past this error?

Hi all,

Browsing all your files on this site i only encoutred CYPD3125 files.

Would really appericiate if you can provide me with the CYPD3120 Code i can Build using PSoc creator and load using USB interface using EZ-PD.

Also, any other SW tips will be helpful.

Thanks,

Ido
