PSM Applications : What's This Fault?

This FAQ Section provides detailed help for faults/warnings/status that you may encounter using various parts with LTpowerPlay.  This is the staging grounds for content that will ultimately be deployed with LTpowerPlay in the "What's this Fault? Tool".  Some of this content may be in draft form, so please bear that in mind when reading it.


The names of the individual pages in this section are titled to match the items that are shown in the FAULT_WARN_LIST pseudo-register in LTpowerPlay.  This pseudo-register is visible in the Telemetry/Status panel, and summarizes the faults/warnings/status for the selected channel.  A new tool called the "What's this Fault? Tool" lists each of the statuses shown in the FAULT_WARN_LIST register and allows you to get detailed help on the selected status item of interest.  The content from the subpages of this section are displayed when you select an item in the "What's this Fault? Tool".

 

Note that this content is under active devleopment, so you may encounter scenarios where the selected status item does not yet have detailed help.  In this case, LTpowerPlay will tell you that no content is available and will direct you to the part's datasheet for further information.  If you have encountered this and the content is not located in this section, and you still need help, please contact your local LT Field Sales representative for further help.
