USB EZ-PD™ Type-C Forum Discussions
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.Show Less
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.Show Less
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.
For one of the application we are planning to use CCG1 as a Power delivery. My question is does the functionality of switching (Vsel1 and Vsel2) between the voltages inbuilt to the controller or do we have to switch some internal mux or control the Vsel1 and Vsel2.
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 directlyShow Less
