AM2434: Power down sequencing

Hello Koichiro Tashiro

Thank you for the query.

Since AM243x operates core operates only at 0.85V, the above sequence seems Ok.

Hi Sreenivasa,

The customer wants a clear answer from TI. "seems Ok" is not enough.
Could you give me Yes or No?

Thanks and regards,
Koichiro Tashiro

Hello Koichiro Tashiro

Thank you.

According to datasheet section 6.10.2.2.2 Power-down sequencing diagram, there seems no power down order requirements among power supplies.
All power supply rails can be shut down at the same time. Is this correct?

Yes.

Do note that the MCU_PORz should be driven low before the supplies ramp down.
