Part Number: DS90UH926Q-Q1
Other Parts Discussed in Thread: DS90UH925Q-Q1,

Hi team,

My customer wants to know whether DS90UH925Q-Q1 has the same power-up sequence as
DS90UH926Q-Q1 regarding VDDIO and VDD33.

I could't find power-up sequence description regarding VDDIO and VDD33 in the DS90UH925Q-Q1 datasheet.
But, please let me know.

Best regards

Hello,
Similar power up sequence can be used for the 925. VDDIO and VDD33 can either power up separately (VDDIO comes up before VDD33) or both supplies may ramp at the same time, but not VDD33 before VDDIO.
