I want to solve my problem.
When I click EZ-PD Protocol Analyzer Utility Windows.exe on the above page, it is not running.
Is there a solution?Show Less
I am trying to use this chip and wanted to work from the design example of the EVB (CY6611 EZ-USB HX3PD Hardware Design). My issue is that I am using Altium 21 and the file will not open because it says I need Cadence Allegro on my system to open. Is there a way to get the file in a format that I can import into Altium?Show Less
我在完成power negotiation后设置了一个标志位，在while循环里面判断到标志位后直接调用dpm_pd_command API 发送discover identity会提示失败（返回的错误为CCG_STAT_BUSY），但是使用一个10ms period的timer，在定时器回调上调用dpm_pd_command API 发送discover identity，却是正常的，请问原因是什么？另外使用dpm_pd_command发送PD命令的正确做法应该是怎么样的？Show Less
I have been using the CYPD3177 IC on a product for the last 6 months or so, and was looking to add it to a new product. This is an active part but I see no supply for at least the next several months. What is happening and can I expect difficulty obtaining this part going forward? Is there a substitute option available?Show Less
Hello, I am currently developing a USB PD power bank that utilizes bi-directional 60W input and 100W output. My plan is to use SC8815 I2C bidirectional buck-boost controller for Power and CYPD 3171 as the PD controller. I want to use CYPD3171 to control SC8815 over I2C to configure SC8815 modes(input and output) as well as output and charging voltage, etc. I also want CYPD3175 to inform the main MCU of PD modes, voltages, currents etc. My question is that what is the best way to achieve this functionality? Should I use EZ-PD config utility or PSOC programmer to write the code? Also, how should I upload the program onto CYPD3175, can I use an ST-Link, or use another MCU over I2C? Can someone recommend me a software and programmer combo? I saw this reference design using sc8915 which is extremely similar to my application, and I think I am going to reference the schematic, but I don't see where the code is located, could someone also inform me of where it is located so I can use it as a reference if possible? I am new to the CCG3 ecosystem, thank you very much!
I have some question about how to install EZ-PD™ Protocol Analyzer Utility (USB PD3.0).
We installed EZ-PD™ Protocol Analyzer Utility (USB PD3.0).
However, the attached message is appeared and cannot execute...
*EZ-PD™ Analyzer Utility (USB PD2.0) is installed and we can use.
Hi All -
I'm not 100% certain that this is the right location for this discussion, so my apologies if it is not.
I'm trying to understand how the USB PD specification requires the handling of a situation where a PD Source offers a power rating in one of its PDOs that is higher than a PD Sink requires.
For example, in my application I'm considering configuring my CCG2 with the following Sink PDOs:
- 5V@3A [15W],
- 9V@2.8A [25.2W],
- 15V@1.8A [27W].
My application uses a charger that would likely draw 2.64A@9V or 1.66A@15V . At 5V my charger would like to draw 3.6A, but the charger is limited to an input current of 3.3A, so I think a 3A PDO limit is fine as I'll software limit the charger.
My confusion is how the CCG2 will negotiate with various off-the-shelf chargers that are available on the market. For example, the Nintendo Switch and Apple MacBook chargers offer the following PDOs:
Now, when I plug my device into the Switch charger, which of my configured PDOs will it default to? My highest PDO power draw is 27W, so will the Switch output my requested 15V@1.8A or will it provide me with 9V@3A which seems to be a standard 27W supply...
The same question happens for the MacBook charger. If I plug that into my device, then which PDO will be negotiated?
Let's also assume that my highest PDO option was actually 15V@2A instead of 1.8A for a power draw of 30W. In that case, would the Switch negotiate 15V@2A even though that isn't one of the listed PDO that it offers? And the MacBook charger... What would that output?
Hopefully this information will be useful to others as well. I can't seem to find clear examples of these negotiations anywhere else.
I have just started with this board. I installed EZ-USB HX3PD Configuration Utility but in the Update Manager, it is showing me network error. I exited from Update Manager and then restarted from start menu, it opens EZ-USB HX3PD Configuration Utility window. I can't find any document to upload their.
Can anyone help me with this?
