Tool/software:
Hi team,
I am using the DP83867IS in dual power supply mode.
When the power is turned on, the following waveform appears and I have two questions.
①
When VDD1P0 is applied, VDDIO becomes 250mV. Is this a problem?
This does not occur when VDD1P0 is not applied, so I think it is a leakage current inside the DP83867.
②
When the 3.3V inside the board rises, 650mV is applied until VDDIO (1.8V) rises.
This is due to leakage from another circuit. Is this a problem?
Best regards,
