Hi,

I need to deal with a case where the input power source is suddenly OFF.
I saw that when VDDIN_PWR_BAD_N go active the Xavier initiates a controlled shutdown:

  1. What does exactly mean?
  2. how much time does it takes?
  3. How much power do I need to supply for the shutdown to occur as planned? (I’m using external capacitors)
  4. Can I immediately shut down all power without damaging the device?

Thank you,

Hi, the power down timing is guaranteed by power discharge circuit as you can see in OEM DG. It is not so critical. There are some timing value for reference in DG. Immediately shut down is not good to all electrical components even though it won’t cause damage to device in general.
