Hello Kallikuppa Sreenivasa.
For DP83TG720R-Q1
Will the PHY enter the sleep mode automatically when only VSLEEP Power is provided and the other Power rails are disconnected ?
Your answer:
The device will be in a mode similar to the sleep mode when all the power supplies are cutoff.
However, INH will be still high. This will take extra current of VSLEEP/R, R is approximately equal to pull down resistance on INH.
In his case INH is unusable for connecting to PMIC.
Will the new PHY DP83TG721 enter the sleep mode automatically when only VSLEEP Power is provided and the other Power rails are disconnected ?
Best regards
