Are there any known requirements to power sequencing between the 2 power rails of PCAL6408?

Hi Thomas,
There is no power sequence requirement for these two power rails. If I/O interface is not powered then nothing works since core operation is from I/O power (VDDP) and POR circuitry is also off.
Best regards,
Tomas
