ADS54J66: Power Sequencing Wrong. Just reset?

Jake Hillard

Part Number: ADS54J66


Hi Jim,

The 2017 datasheet references IOVDD power must come up before DVDD power, or "the internal default register settings may not load properly".

If I bring them up out of sequence, but then hit the reset to restore defaults, would this be sufficient to return to a known state?

Thanks,

    Jake,

    If the device did not load the internal fuses properly during power up, the only way to fix this is to cycle power. If you are not doing the power sequencing per the data sheet, this power cycling may or may not fix the issue.

    Regards,

    Jim
