ADS8557: Power Supply Sequence

Part Number: ADS8557

Hi,

It is written that "when HVDD is supplied before AVDD, the internal ESD structure conducts, increasing IHVDD beyond the specified value. " on the datasheet.

If the current doesn't flow through internal ESD, should we begin to turn on HVDD after AVDD finishes to turn on definitely ilke following①?

Or, can we begin to rise up HVDD soon after AVDD begins to rise up like following②?

Best Regards,
