VBUS不切换到其他电源配置电压

嗨，Rajath，
我分享的原理图是最初的版本，我稍微修改了原理图。我已经添加了一个与MOSFET栅极和CGG2引脚21和24串联的68 K电阻，之后，cc1和cc2引脚开始切换到40ms。
我问的5V电流要求的原因是使用LDO代替开关稳压器。在当前的电路图（主项目）中，我们有一个开关稳压器，它提供高达6A的电流，并且已经连接到双P通道，但是当我们没有从开关稳压器中汲取电流时，工作电流将比操作电流O高一点。F LDO。为了减少理想模式下由系统引起的输入电流，我们正计划使用LDO来驱动双P沟道MOSFET，并且在理想模式下系统关闭开关稳压器。
我们在不断地测试董事会，而CGG没有停止工作。一旦年停止工作我将检查你所用示波器的点和分享你的照片。
谢谢，
纳加拉杰

  Hi Rajath,
 
The schematics which I shared is the initial release and I have slightly modified the schematics. I have added a 68K resistor in series with MOSFET gate and CCG2 pins 21 and 24, after which the CC1 and CC2 pins started toggling at ~40ms.
 
The reason why I asked about the 5V current requirement was to use a LDO instead of switching regulator. In the current schematics (The main project) we have a switching regulator which will provide up to 6A of current and the same has been connected to dual P channel, but when we are not drawing the current from switching regulator the operating current will be bit higher than the operating current of LDO. To reduce the input current drawn by the system in Ideal mode we are planning to use LDO to power dual p channel mosfet and switch off the switching regulator when the system in ideal mode.
 
We are continuously testing the board and the CCG didn't stop working. Once the CCCG stops working I will check the points you mentioned using oscilloscope and share you the pic.
 
Thanks,
Nagaraj

嗨，Rajath，
请让我知道应该是什么容量的5V POSER电源，将连接到2-N通道FET。
谢谢，
纳加拉杰

  Hi Rajath,

Can you please let me know what should be the current capacity of the 5V poser supply which will be connected to 2-N channel FET.
 
Thanks,
Nagaraj

你能附上修改的示意图（VBUS切换部分）吗？
我会告诉你的。
谢谢，
拉贾斯

  Can you attach the modified schematic (Vbus switching part)?
I will go through and let you know.
 
Thanks,
Rajath

嗨，Rajath，
我已经和大家分享了这些原理图（分享其中一篇文章）。
在我们的应用中，我们使用的是5 V降压转换器，当没有负载时，我们计划关闭降压转换器，但是在当前的释放中，如果我们关闭降压转换器，CC线路将在3.3V（也为了节省功率）在我们计划的下一个版本中切换。将LDO添加到功率2-N沟道MOSFET和降压转换器将在某些事件之后开启。
因为这个原因，我问的是当前的容量是多少。5V/500毫安LDO是否足够？
谢谢，
纳加拉杰



     以下为原文
  Hi Rajath,
 
I have already share the schematics with you (Share in one of the post).
 
In our application we are using a 5 V step down converter and when there is no load we are planning to turn off the step down converter, but in the current release if we turn off the step down converter, the CC lines will be switching at 3.3V (Also to save power) in the next release we are planning to add a LDO to power 2-N channel mosfet and the step down  converter will be turned on after some event.
 
For this reason I was asking what should be the current capacity required. Will a 5V/500mA LDO will be sufficient?
 
Thanks,
Nagaraj

嗨，Rajath，
的ccg2装置停止工作，我们有以下的信号测量，
1。VBUS：0V时，没有电源适配器连接。当电源适配器连接的VBUS是切换（5V和0V）。
2。VCCD：1.8V
三。VDD，VDDIO：3.38伏
4。CC行：0V（不切换到40ms）。
5。XRES:3.38伏
6。I2C线：I2C线与其他设备一起工作。
请让我知道，如果你需要更多的信息。请注意所有的读数都是用示波器拍摄的。
谢谢，
纳加拉杰



     以下为原文
  Hi Rajath,
 
The CCG2 device stopped working and we have measured the below signals,
1. VBUS: 0V when no power adapter is connected. When power adapter is connected, the VBUS is toggling (5V and 0V).
2. VCCD: 1.8V
3. VDD, VDDIO: 3.38V
4. CC lines: 0V (Not toggling with ~40ms).
5. Xres: 3.38V
6. I2C lines: I2C lines are working with other device.
 
Please do let me know if you need more info. Please note all the reading are taken using oscilloscope.
 
Thanks,
Nagaraj

嗨，Nagaraj，
你有柏树的CGG EVK吗？
我无法将问题定位在电源适配器或笔记本上。
如果你有ccg EVK，我建议测试这个：
您的CGG2笔记本电脑& CCGx EVK &作为电源适配器
CCGx EVK作为接收器&您的CG2电源适配器
试着测试这两个场景来独立测试两个板。那么，调试连接时发生的事情就更容易了。
当做，
拉贾斯



     以下为原文
  Hi Nagaraj,
 
Do you have a Cypress's CCG EVK?
I am unable to localize the problem whether it is on the power adapter or notebook.
I recommend testing this if you have CCG EVK:
 
your CCG2 notebook <-----> CCGx EVK as power adapter
CCGx EVK as sink <------> your CCG2 power adapter
 
Try testing these two scenarios to test your two boards independently. Then it will be easier to debug what happens when connected mutually.
 
Regards,
Rajath

嗨，Rajath，
我们没有EVK和我们在一起。我们有一个板配置为电源适配器和一个板我们已经配置为笔记本电脑应用。这种情况只会在笔记本应用中出现。
如果没有EVK，我们有没有办法检查？
谢谢，
纳加拉杰



     以下为原文
  Hi Rajath,
 
We don't have EVK with us. One board we have configured as power adapter and another board we have configured as notebook application. This condition will come only in notebook application.
 
Is there any way we can check this without EVK?
 
Thanks,
Nagaraj

嗨，Nagaraj，
请再次检查如果适配器能够通过协商提供12V。
比赛在VBUS意味着什么是协商的PDO和活性PDO的错误。
这将要求CC日志进行调试。请尝试使用cy4500 CC协议分析仪读取通信。
只有这样才能使我们走上正确的道路。
当做，
拉贾斯



     以下为原文
  Hi Nagaraj,
 
Can you please check again if Adapter is able to provide 12V after negotiation.
The race around in VBUS means something is wrong with the negotiated PDO and active PDO.
This will require CC log to debug. Please try to read the communication over CC using CY4500 protocol analyzer.
Only this will take us in the right direction.
 
Regards,
Rajath

嗨，Rajath，
我们没有CY4500协议分析器来调试CC引脚。



     以下为原文
  Hi Rajath,
    
we don't have CY4500 protocol analyzer to debug the CC pins.

嗨，Nagaraj，
1。请问你在CC线上有没有SooCixICAP广告？（这个问题基于CYPD2134连接到CYPD2122）。如果是，CYPD2122是否已请求12V电压？如果没有，你需要参考第2项。
2。如果在CC附加状态下没有任何CC协商。请分别检查CYPD2134和CYPD2122。
CYPD2134，Cc1和Cc2高达4.0V。
GCPD2122。预计CP1和cc2的时间间隔约为40ms。
当两个C型插座通过C型电缆连接时，cc1和cc2中的一个应具有1.68伏（或0.9V或0.45伏）的分压值。
三。在CC线路上有正确的分压，我们可以在CC线路上寻找SooCeCyPad。如果没有广告，请检查硬件相关的cc1和cc2。
最好的问候，
丽莎

  Hi Nagaraj,
 
1. May I know whether you have got SOURCE_CAP advertise on CC line or not? (This question is based on CYPD2134 connect to CYPD2122). If yes, whether CYPD2122 have been request 12V voltage or not? If no, you need refer item#2.
2. If there is not any CC negotiation on CC attached status. Please check CYPD2134 and CYPD2122 separately. 
>> CYPD2134, it is expected CC1 and CC2 is high to ~4.0V.
>> CYPD2122. It is expected CC1 and CC2 is togged with time interval about 40ms.
>> When two Type-C receptacle connected via Type-C cable, one of CC1 and CC2 shall have a ~1.68V (or 0.9V, or 0.45V) divide voltage value.
3. With the correct divide voltage on CC line, we can looking for SOURCE_CAP on CC line. If there is not any advertise, please kindly check hardware related CC1 and CC2.
 
Best Regards,
Lisa

嗨，Nagaraj，
伟大的。如果是这样，梅，我知道您是否已经按照您的项目定制了函数BoOL SETIPSPSRCY电压（UTI1616T Value50MV）@文件Pase.C？
您可能注意到，OrnIAL固件代码仅包括5V、9V、15V和20V。在您的CYPD2134项目中，希望您在交换机（Value50MV）下添加一个实例，如下所示：
VBSU1212V：
VSEL1X写入（XXXX）；
VSEL2X写（XXXXX）；
断裂；
最好的问候，
丽莎



     以下为原文
  Hi Nagaraj,
 
Great. If so, May I know whether you have been customized function bool set_psrc_voltage(uint16_t volt_50mV) @ file psource.c as per your project?
 
You may noticed that Orignal firmware code only includes 5V, 9V, 15V, and 20V. In your CYPD2134 project, hope you have add one case under switch (volt_50mV) simillar as below:
        case VBUS_12V:   
            VSEL1_Write(xxxx);
            VSEL2_Write(xxxxx);
            break;
 
Best Regards,
Lisa

嗨，Nagaraj，
你能成功切换到其他配置9V和20V？
你在GPIO中试用过GPIO而不是默认的，用于生成VSEL1和VSEL2吗？
当做，
拉贾斯



     以下为原文
  Hi Nagaraj,
 
Are you able to successfully switch to other profiles 9V and 20V?
Have you tried GPIO's other than default ones in the firmware, for generating VSEL1 and VSEL2?
 
 
Regards,
Rajath

嗨，Nagaraj，
1。由于您只在VBUS上观察到5V，所以您只能得到VSEL1／2输出到0。合同完成后，最新合同为5V。
2。如果您愿意调试这个问题。我想向您推荐关于VBUS和VSEL1／2的进一步细节。如果你有PD协议分析器会更好（例如，CyPress CY4500工具包可以帮助你）。这样就可以知道在12V电压合同中是否有任何故障。
三。从你的描述，你说固件已经运行12V的情况下。CGG2不仅去那里设置电压。你知道固件里面有很多定时器，VBuxMon将在这个动作之后工作。
请将详细的波形和CC通信日志与我们分享，以便进一步调试。
最好的问候，
丽莎



     以下为原文
  Hi Nagaraj,
 
1. Since you only observed 5V on VBUS finally, you will only got VSEL1/2 output to 0. Since the contract is completed, the latest contract is 5V.
 
2. If you could like to debug this issue. I could like to recommend you further details measure on VBUS and VSEL1/2. If you have PD protocol analyzer will be better (For example, Cypress CY4500 Kit can help you) . So that we can know whether it is any failure on 12V voltage contract.
 
3. From your description, you said the firmware have been run 12V case. CCG2 is not only go there to set voltage. You knew there are many timer inside of firmware, VBUS_MON will be work after this action.
 
Please share details waveform and CC communication log to us to further debug.
 
Best Regards,
Lisa

嗨，Nagaraj，
如果你使用CY4500分析器，你能分享CC日志吗？那很有帮助。
否则，可能需要调试示意图和/或项目细节来调试这个问题。
最好的问候，
拉贾斯



     以下为原文
  Hi Nagaraj,
 
Can you please share the CC log if you are using the CY4500 analyzer? That will be very helpful.
Otherwise, schematic and/or project details maybe required to debug this issue.
 
Best regards,
Rajath

嗨，拉杰斯/丽莎，
我们没有CY4500分析仪。适配器最初没有将VBUS电压切换到12V，而当我们再次用相同的应用重新闪动电路板时，适配器板开始将VBUS切换到12V。
我们面临另一个问题，CYPD2122笔记本应用停止工作，CC线将不会切换到40ms，I2C将不响应，在这种情况下，我们必须重新闪光控制器，然后它开始工作。
我们想知道这种行为的原因。
注意：我们在安装SDK时没有改变CYPD2122笔记本应用程序中的任何代码。
谢谢，
纳加拉杰



     以下为原文
  Hi Rajath/Lisa,
 
We don't have CY4500 analyzer. The adapter was not switching the VBUS voltage to 12V initially and when we re-flashed the board again with same application then the adapter board started switching the VBUS to 12V.
 
We are facing another issue, the CYPD2122 with notebook application stops working, CC lines will not toggling at ~40ms  and I2C won't respond, in this case we have to re-flash the controller and then it starts working.
 
We would like to know the cause for this behavior.
 
Note: We have not changed any code in the CYPD2122 notebook application which we got while we installed the SDK.
 
Thanks,
Nagaraj

你好，Nagaraj，
1）在什么时候它停止工作？有没有一个时间段，或者，一些电缆断开连接动作，或者电源循环，或者什么之后你观察到这个？
2）I2C没有反应是什么意思？你是说HPI接口吗？
3）如果您不遵循CGG2数据表上的应用程序图，请查看是否可以提供您的示意图，这将非常有帮助。
4）你能在停止工作时测量这些点的电压吗？（示波器轨迹会更好）
VBESIDCC CC LISESVDDD，VCCD和VDIOI2C-SDA，I2CYSCL，XRESE
最好的问候，
拉贾斯



     以下为原文
  Hello Nagaraj,
 
1) At what point of time does it stop working? Is there a time period, or, some cable disconnect - connect action, or, power cycle or anything after which you observe this?
 
2) What do you mean by I2C doesnt respond? Are you talking about HPI interface?
 
3) If you are not following the application diagram as on CCG2 datasheet, please see if you can provide your schematic, it will be very helpful.
 
4) Can you please measure the voltage at these points when it stops working: (oscilloscope traces would be even better)

• VBUS
  
• Both CC lines
  
• VDDD, VCCD and VDDIO
  
• I2C_SDA, I2C_SCL, XRES
  

 
Best regards,
Rajath
