TE0813 SoM MotherBoard design

[Guillaume]

Hello,

I am currently designing a MotherBoard to support the SoM TE0813.

I would like to be sure I understood correctly the power on sequence:
First I need to provide the 3.3V called 3.3VIN before anything else.
Then I can connect to the same 3.3V PSU all the rails (PL_DCIN/DCDCIN/LP_DCDC/GT_DCDC) and enabling them according to sequence by using the dedicated ENABLE pin.(Enabling when receiving the previous "Power GOOD" signal) Is this correct ?

What about the turn off sequence ?

Thank you in advance,
Guillaume
