USB EZ-PD™ Type-C Forum Discussions
Hello
In section 10.4.1 (Control of VBUS Provider Path and VBUS Consumer Path) of the Hardware Design Guidelines for the DRP Applications Using EZ-PD USB Type-C Controllers (AN210403), the circuitry shows a series of transistors without any list of specific components. What are the actual components for Q1, Q5, Q6, and Q16 on this page?
Thanks,
Hal
Hello
I am interested in making current and voltage measurements on my device. For this purpose I used cy4500 protocol analyzer. I was able to display graphs of voltage and current however I would like to get more accurate information to perform calculations of average current, average power and more.
I understand that all the information is saved in the .ccgx3 file
The user manual states that
Note: * .ccgx3 file is a proprietary Cypress format. Files stored in this format can be opened using any XML editor.
I tried to extract the information from the file but could not even open it. I would be happy for your help with what software can I open the file?
Or if there is another method to get accurate measurements of current and voltage consumed in the device, for analysis?
thanks, Geva
Hi,
I am planing to use the CCG3 CYPD3171 for portable powerbank, and I am not very familiar with this USB-C controllers. Since I will use it in power bank I will need only the USB-C contract establishing and I2C to communicate with the main MCU.
I watched the training videos provided from Cypress, but I didn't understand is the controller coming preprogrammed and can use it directly or need only configuration, or I have to program it ?
Thanks in advance!
Hi all,
How can I get the .IBIS model for CYUSB3065-BZXI, thanks!

Hi.
I have an application where I want to configure multiple PDOs on the CYPD3177 chip. I see that this is possible using the HPI over I2C. I already have an external MCU in my application that I can use to do this so this is not a problem. If I am planning to do this, is it okay to leave the configuration pins that are usually connected to a resistor divider network (VBUS_MIN, VBUS_MAX, etc.) not connected/floating?
Thanks,

Customer refer to datasheet - Figure 14. USB Type-C to HDMI Adapter Application schematic.
now has two question:
1). what purpose does it provide two power path to CCG3 ? (1). VCONN connect to Vsys pin (2) . VBUS internal LDO?
2). if connecting HDMI only and dis-connecting c port, why ... you can measure 2.8V on Vddio pin?

I try to design USB 3.1 gen 2 TYPE C with PD using CYUSB4347-BZXC Chip.
Application is USB Dock with bus power.
I'm designed to USB circuit for the first time, so I don't really understand USB design.
I thought that the CY6611 EZ-USB HX3PDEVK would be good if the circuit was changed from self-power to bus power.
Please see the attached file that draw the Block Diagram.
(DS2~DS7 is not use this time ,but will use in feature.)
I don't know how it works with this block diagram configuration as USB TYPE C DOCK using bus power.
Is there any problem about this block diagram configuration?
Or Is there a better circuit configuration?
Would you tell me advice?
Best Regards,
Takashi Igarashi

We are going to use CYPD3120 in our design along with TI cross-switch TUSB564RNQT. Please have a look on the questions along with block diagram. (please note that I have already asked these questions in another post but I wasn't able to get the answers);
1. Please have a look on the block diagram for CYPD3120 (we will be using power from USB-C only and acts as upstream facing port), and kindly let me know if it supports by default the addition of cross-mux as marked in red or we have to alter the firmware?
2. Please clarify about the firmware updates. I can see that these chips has SWD interface to program the flash and along with it is also mentioned in that datasheet that the devices have default firmware, for example CYPD3120 has default FW of USB Bootloader. I am assuming that it means we can program the CYPD3120 via USBC? Also, once the firmware is loaded then we don't need to program or boot it via USB or I2C each time? Actually this may help us to eliminate the addition of Embedded Controller on the board.
3. Lastly, the CYPD3120 will be using USB 2 lines for Billboard support but at the same time the USB 2 lines will be going to the USB hub. I have added the green lines in above block diagram. Usually we can do it if the USB2 lines are just used for charge detection and we can connect them to the PD and stub along with passing the USB 2 lines onwards to the HUB or any other location. Do you think it will be OK to do so in this case where the USB2 lines will be used by CYPD3120? If this is not possible then may be we can connect it via DNP to CYPD3120 and use the billboard support within the hub.
These points are important before implementing it and due to time constraint I would really appreciate a reply on these above points.
Thanks and regards,
Muhammad Awais

Dear All,
My plan for Project type-c monitor:
1. Base on project example 3120 dp dongle
2. rebuild boot loader for 3121
3. change device to 3121 and SID from 1D00 to 1D02
4. update config by EZ-PD configuration Utility
My questions are:
1. Am I miss anything for this plan?
2. Currently, the VBus is 0V on my PCBA , but my configuration is 5V, can anybody give me a direction to fig out it , thank you very much.
Best Regards,
King
