Hello

They want to use CYPD3171-24LQXQ without PD function and only with Power-SINK. In this case, Please tell me the setting to disable the PD function.
Or  there any method to disable the PD function?

Best Regards

Mac/Arai

Hello,

What is the thing that customer really want to do?

Even if CCG3PA is PD contracted, CCG3PA can send RDO as 5V/0.1A (0.5 Wattage) at the minimum to the Source.

Obviously, 5V/1.5A, 5V/3A, etc Sink PDO is also able to set for CCG3PA.

In addition, if the power source is not a PD compliant (does not send Source Capability, etc.), PD negotiation obviously does not start.

If they still would not like to have a PD function on the CCG3PA side, they need to modify the CCG3PA Firmware or request Cypress to develop the specific Firmware.

Best regards,

Hirotaka Takayama
