Re: Power sequencing issue 7030

Is this your own carrier board or a commercial one ?

Re: Power sequencing issue 7030

Ok, so it could be a range of things.
Have you tried the picozed in a reference carrier to prove that it works as you understand it ?

Yes , I have tired it , on Picozed Eval board also it works find ,

 

Previously I have made one more carrier board with ADP2323 reg it works fine in that design too. 

 

In the shared design it is not working I am getting VCCIO , & PG_MODULE
