Team,
My customer has the following questions per the data sheet.
I had a couple of questions:
1. We plan onusing this in both Host and Device Mode. We have been struggling with how
to hook up the CPEN and Vbus signals to support both modes. My assumption
would be Figure 10-1 would cover both options where as Figure 10-2 is a Device only
mode.
2. Do you havea suggestion for a Vbus switch to use with this component. There are
quite a few on TI, and it was not obvious what would be the best solution.
Our driving requirement is cost and -40 to 105C temp range. We also
need lead-free.
3. Per Figure 5-1, it shows that Vdd33 (3.3V) should come up before Vdd18 (1.8V).
However, no additional information is provided on the requirements for
that power sequencing. We have an issue on our board in which all of our
other multi-voltage devices require 1.8V to come up before or at the same time
as 3.3V. What would be the implications of bringing up 1.8 before 3.3 or
at the same time?
Regards,
Aaron
