     Dear all,

 

Our company is a wireless charging Soc company,the photo #1 is our Tx demo board,he can support PD 、QC、 PPS and other protocols,

Normally our Tx demo board can tramsmit under 40W to our Receiver demo board.

But if the inserted cy4500ez-pd takes a long time to appear 20 lines and then never shows up again (photo#2).!!!( The board is still transmitting power),

  • our TX board only be used Sink.
  • The GUI-> CC Termination Settings  -> CC Line 1orCC Line 2,  all have been tried,but i donot know it is right or true.
  • which configuration i miss did?

I want to use cy4500ez-pd read protocol message,colud you tell me what should I do?

if anyone have any suggestion o rquestion  please tell me .

Hi ,

从CClog上来看没有什么问题,首先UFP要求了5V,然后要求9V,然后就没有交互了。 然后9V就在VBUS上一直存在。这是符合PD SPEC。

您期待的是什么数据呢?

Best Regards,

Lisa

Hi,

我想要的是时时更新的数据,比如我充电10分钟,那么就有这一阶段的数据;

现在我拿开或者拔掉或者重启都没有那一时刻变化的数据.

Hi ,

右上角的VBUS voltage是事实会更新的。

蓝色部分的是CC message,如果没有CC message,它不会被更新,指导下一次有CC message才会记录当时的VBUS电压和电流。
