LM5176-Q1: Is there a pin FMEA available for this part?

Thank you very much for the document - this is very helpful.

I am curious as to why internal shorts to VIN are not included in the analysis.  That seems to be included in the other TI  FMEA analysis for potential package failures: pins open, pins shorted to adjacent pins, pins shorted to ground, and pins shorted to VIN.  Is there a reason the short to VIN does not need to be considered for this IC?

Thanks!

Hi Jessica,

this are included, see row 11 and 14 - or do you ask for something else?

Best regards,

Hello Stefan,

For example, the buck regulator LM63635-Q1 includes a table of short circuits between any pin on the IC and VIN:

This seems pretty consistent for all the TI functional safety analyses.  

Hi Jessica,

let me check with the expert on FMEA and come back beginning of next week.

Best regards,

Thanks - I look forward to hearing from you.
