Other Parts Discussed in Thread: TIDA-01243, , TUSB8041, TPS65987D
My customer is using the TIDA-01243 as a starting point and is adding an additional HDMI port as well as replacing the NRND TPS65986 with the TPS65982.
Here are the customer questions... please contact me for the Block diagram/schematics. I will not post them here.
- A fundamental question on the U52 (currently TPS65986). The way I understand this IC is that he controls the Type C USB by identifying insertion/de-assertion, cable orientation, and then manages power negotiations. The way it does all of this is using the CC1/CC2 pins. For power negotiations though, does it communicate with the host (PC) which then manages the power of the system? I guess what I am getting hung up on is when does it charge with 20V/5A, 20V/3A, or 5V/3A, etc.? U52 is not connected to U24 (TUSB8041), so how can it manage charging?
- I am replacing U52 with TPS65982 which has a few more signals that I think I terminated properly. I am leaving the HV Gates open and so then this becomes a drop in replacement, correct? And this is the right move, correct?
- Eval board audio doesn’t work - looking to replace with the PCM2912A because a MIC input is needed. But would like to know why the TIDA-01243 audio does not work.
- USBA port loses charging capabilities when USB C connection is lost.
- Programming (TIDA-01243 ICs) – Do we have to worry about programming anything? How to do it? Etc.
Thanks!
