Other Parts Discussed in Thread: TPS65910A

Hi,

I about starting time of the power supply sequence of AM335x

There is a description of the start-up sequence of the power supply to P99 page data sheet (SPRS717F) for start-up time of the power supply sequence of AM335x, but I do not mention that a temporal.

Is it all right do not you think?

 

In addition, there is a description of the OSC0 to P108 page data sheet.

And to launch a VDD_CORE it after launch VDDS_OSC

Or do I assume how much time?

 

best regards

hamada

    Hi Hamada,
     
    There are no specific timing requirements for the power-on sequence. Just the correct switch-on order must be followed, and make sure to read the notes below the power-on diagrams, which specify additional requirements. If you take the TPS65910A PMIC as a reference, it is designed to turn on power supplies at approximately 3ms time slots.
     
    VDDS_OSC is a 1.8V power supply, so it should be turned on along with the rest of the 1.8V supplies.
