Hi I have a project on hand to use CCG3 and NCP81239 as USB Type-C PD3.0 charging station. Can I use CCG2 60W Car Charger Reference Design as a design reference guide. My charging vault charge 10 HP USB C NB power bank or HP Notebook power bank, charge time for HP notebook power bank is less than 4hr, for HP USB-C NB power bank is less than 1 hr. Both of them are 6 cell 19200mAH. 6 set of voltage 5V, 9V, 10V, 12V, 15V, 20V all with output current of up to 3A. 

Hi,

I am not sure whether this is the right place to ask this question.

I am new to CCGx and billboard device. I received a request from customer which asks me to build something with a single billboard device connects to two CCG2 devices. I know billboard is used to negotiate with host about what alternate mode the container device supports.  But the specification doesn't disclose more detail about it.  So I have some questions, hope someone can help to answer it.

1. Does billboard detect the alternate modes or the modes are pre-defined in its firmware?

2. Can single Billboard serve multiple CCG2 ?

3. Will CCG2 write back some data to Billboard?

Thanks a lot.

Dear Cy tech team,

      Could you please explain me the role of CCG1 in this design? I think Type C to Legacy USB can be achieved with a single resistor. Please correct me if I'm wrong.

Tnx

I would like to use CCG2 for USB Type C Paddle card but I would like to know how to connect the connect shield to ground directly
