DP83867CR: Powering down sequrnce

Masakazu Adachi

Part Number: DP83867CR

Hello team,

I received a question about the powering down sequence from the customer. If turned off in the order VDDA1P8 -> 2P5, is there any risk of device damage etc?

Regards,

Hi Masa-san,

There is risk if this procedure is not followed as the 1.8V can potentially backpower the 2.5V rail, thus potentially damaging anything else sharing the 2.5V line.

Sincerely,

Gerome
