Part Number: TUSB1046A-DCI
Other Parts Discussed in Thread: TUSB8044A, TUSB1064

Hello,

Please see my simplified Block diagram below.

I am working on the following HUB design:

INPUT: the USB-C Host (PC or Laptop)

OUTPUTS: 4x USB-C + Display Port

QUESTIONS:

1. Is the Block diagram (with TUSB1046A, TPS65983 and TUSB8044A) correct approach?

2. Since I will not use the outputs of the HUB for charging and the USB-C outputs will be very low current (I will need USB-C Host current setting for fixed value of 1.5A), could I use the simpler approach for PD Controller than TPS65983? Do you have any recommendation?

Please, see Block diagram below.

Thank you for your help.

For USB Type-C sink side, you will want to use TUSB1064, https://www.ti.com/lit/ds/symlink/tusb1064.pdf.

But you still need a PD controller to support DP Alt Mode for this design.

Thanks

Hi David,

Thank you for the answer and pointing me to TUSB1064 (my mistake it was typo. Yes, the TUSB1064 it is).

I have one more question:

When I have the schematic done, is there somebody who could review it? Please let me know.

Thank you.

Pavel

I can help reviewing your schematic once it is completed.

I sent you a friendship request, would you please accept it? If you are using Cadence Capture, I can send you the TUSB1064 and TUSB8044A board file as a reference.

Thanks

David

Hi David,

That would be great, thank you!

I did accept "the friendship request". And yes, I am using the Cadence schematic capture - the reference board files would be very helpful. I would really appreciate it.

Thank you!
