Hi team,

My customer is using DP83TC811S-Q1.

when setting up sleep mode, and remove the driver code of DP83TC811S (means remove dp83tc811.c), the current is normal,nearly 1.8A;

However when setting up sleep mode and also add the driver code of DP83TC811S (means remove dp83tc811.c), the current is abnormal, nearly 20mA.

Hello Amelie,

I do not understand your system, can you share more information, block diagram etc? What are your PHY voltages? The PHY alone should not consume so much current (1.8 A).

Thanks,

Vibhu
