UCD9248 wiring at KC705

Hi at all,

 

I have some questions concerning the UCD9248 PMBus controllers that are used to power up/down the KC705. Which function do the SRE-1B, SRE-2B, SRE-3B and SRE4-B as well as the FAULT-1B, FAULT-2B, FAULT-3B and FAULT-4B pins of all three controllers have?

 

Is there a documentation about the power management of the KC705 available. I have already read the section "power management" in UG810 page 63 to 68.

 

Thanks and regards,

Michael

Hello Austin,

 

thanks for the provided information.

 

However I don't understand the connection of all three SRE-1B pins by the signal PWRCTL_SRE_GPIO1. From which device is this signal driven (U55, U56, U89)? And which event does effect something?

 

I have the same question for SRE-2B, SRE-3B and SRE4-B as well for FAULT-1B, FAULT-2B, FAULT-3B and FAULT-4B.

 

Thanks for help!

Regards Michael
