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,

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!
