How can I control power sequencing of EVMK2H with PMBus using USB Interface adapter?

Other Parts Discussed in Thread: UCD9090

Hi,

We are using EVMK2H and We want to control power sequence using PMBus instead of MCU. We are using USB Interface adapter for that purpose. How can I control the sequence as mentioned in Table 4.3 of SPRUH02 using PMBus? Is there any example project for that?

This is not the answer I was looking for. Could you please be more specific about UCD9090? Also tell me can I enable/disable any power rail on ucd9090 using fusion digital power designer.

Shehzad,

I am not pretty much familiar about the fusion digital power designer. I would request you to post the query in power management forum to get better advice.

Senthil,

Originally, this thread was moved from Sequencers Forum to keystone device forum by Brad.

Shehzad Ahmed,
I recommend you to re-post it on power management forum and do not mention anything about EVMK2H on it.

Thank you.
