Hi,
I am currently designing an application using USB Type-C as a main power connector.
My power requirements are close to 25W so according to my understanding, I have to use the PD protocol provided by the Type-C Standard.
My power chain looks like this :
- Apple 87W Type-C PSU (PD 5V@2.4A, PD 9V@3A, PD 20@4.2A) <--> Apple Type-C (EMCA) cable <--> My PowerPCB <-> My ApplicationPCBs
- My PowerPCB has a lot of mechanical constraints (size mainly) due to the Plastic enclosure designed for the project and therefore I was thinking about the CCG2 IC to be my PD Delivery controller.
I have a few questions about that IC :
- Can the CCG2 act as an endpoint and negotiate the PDO (9V@3A) with the Apple PSU by itself ?
- If the answer is positive, is that easy to program the CCG2 to behave as described above using the EZ-PD Configuration Utility ?
I'm not familiar with the Cypress development tools but it looks pretty straightforward to use, generate the code and then program using a MiniProg3.
Can you please comment and let me know if the solution suggested above makes sense for my application ?
Best regards,
Mathieu
