USB EZ-PD™ Type-C Forum Discussions
Hello there,
I would like to request a schematic review please. My application has two use cases:
1. Programming: In this case I will be connecting to a computer for programming through USB-UART bridge. Hence why I have the minimum voltage set to 5V and the current set to 750mA.
2. Operating: The other case will be to provide 20V and request up to 3A from the USB PD host supply. Hence why I set it to VMax at 20V
Questions:
1. Because I set the current request to 0.75A to satisfy the programming needs, will it prevent the draw of more current when in the operating use case?
2. On a previous version of this, when I would plug into the wall PD supply, I would hear a component pop, but it would still supply 20V. Do the power FETs and diodes and other passive components look correct?
3. Additionally, do you see anything wrong with using the LM2576S-3.3 to regulate for control level voltage use off of the PD VBUS?
Thank you so much for your consideration!
Best,
Peter

Hi Infineon
Can you offer the CYPD5225/CYPD6127 detail solder reflow profile for SMT reference, Thanks!!
Hi All:
In my design, negotiate with the PD adapter using CYPD4226 to output 15V to power the system.
During debugging, it was found that the PD adapter has already output normal voltage, but CCG4_ VBUS_ C_ CTR_ P1 remains low level and the voltage cannot pass through the MOS-FET.
Use the Logic analyzer to grab the PD negotiation on CC. It is found that the whole process is normal and "PS_RDY" has been obtained.
I am using CYPD4226-40LQXI_ Notebook -> Noboot project.
According to the requirements, some modifications have been made. The top design is shown in a screenshot, and schematic for reference.
Please help check what the problem is.

The HOST project requirement is:
1. don't need to support DP ALT mode
2. USB support USB3.2 Gen2x2
I have some questions about USB3.2 Gen2x2 wire connection.
Do I need an external MUX between USB3.2 signals source and type-c connector?
or we don't need an external MUX and directly connect USB3.2 signals to type-c connector?
Do you have reference schematic for USB3.2 Gen2x2 ?

Hi team,
For USB4 realization, we are using PD controller from Infineon Technologies. The part number for the same is : CYPD6125-40LQXIT. We have datasheet available online but detailed information is missing from it.
Can you please sharethe following documents from Infineon.
Reference Schematics
Reference Design Layout
Reference Design BOM
IBIS Models
Hardware design guide or technical reference manual.
Regards,

Hello Infineon,
I am evaluating CYPD3177-24LQXQ using our developed circuit board.
But this chip didn't work collectly. PD connection didn't work, so we could't see expected voltage(20V) from PD charger.
Now we are checking this board, as a result, we found that this chip didn't generate 1.8V at 24pin(VCCD).
This issue is same as below question(No.351238).
https://community.infineon.com/t5/USB-EZ-PD-Type-C/CYPD3177-Pin-24-VCCD-Issue/td-p/351238
I would like to know the result about this question. And please tell me the solution.
Thanks,

Hello
Q1)
When connecting any 100W PD adapter and BCR, there are cases where VCCD (1.8V) does not rise, or it rises to 1.8V once and then gradually drops to 0V.
What causes can be considered as the reason why VCCD (1.8V) does not rise? If there are multiple causes that can be assumed, please tell me all of them.
Q2)
If BCR is detected Fault signal, will VCCD rise? Or not?
Please tell me the relationship between the above Fault and VCCD.
Best Regards

Could you please give me the EZ-PD™ CCG2 USB-C to DisplayPort reference schematic??
Hello.
My customer is preparing 140W EPR Adapter development. They want to know whether CY4500 supports EPR feature.
I known CY4500 can see EPR packet but it can't decode EPR. Right?
If no, Do you have the update plan supporting EPR analyzer?
The output voltage of 140W adapter is maximum 28V. Is there no problem for electrical specification?
Regards.
Robert.
