Hi Kerr,

Our firmware does not allow the ability to delay the HPD on the TPS65982. Please refer to Figure 10-1 amd Figure 10-2 of the Fimware User's Guide to review how the TPS65982 handles the HPD input. This information can be found on pg. 31 of the following document:

May I know why the application requires a delayed HPD?

Thank you,
Eric

Hi Kerr,

We do not support the PS176, I would recommend getting in touch with Parade on the functionality of that part.

Thank you,
Eric
