PCA9546A: About FMEA information

Hello Yusuke-san,

Is the customer looking for a pin FMEA (addressing what could happen if various pins are shorted or open) or a design FMEA (detailing internal functional blocks and the impact of their failure at the IC level)?  Are there any example documents you could provide for reference?

Thank you,
Max

Hello Max-san,

Thank you for your response.
Customers want Pin FMEA.
Although the products are different, the customer wants the following materials from TI.

Yusuke-san,

The document is in work now with the goal to complete this week.  In order to simplify the document, could you please let us know which specific package option is needed?  This will influence which pin-to-pin shorts need to be considered.
