DP83867IR: Power down sequence

Kazuki Itoh

Part Number: DP83867IR

Hi team,

In the power supply recommendations, it is mentioned that the 1.8-V supply should be brought down before the 2.5-V supply.

Does it mean it is possible to damage the device if the 1.8V is still there when 2.5V is 0V?

Thank you for the query.

In 2 supply mode the 1.8V is derived from 2.5V input.

In three supply mode you are connecting the 1.8V additionally. 2.5V is 0V and the 1.8V being present is not a recommended operating condition.
