TLIN1431-Q1: Safety mechanisms to increase Single Point Fault Metric to > 90%

Isabel Epple
Prodigy 210 points
Part Number: TLIN1431-Q1

Tool/software:

For our system ASIL-B coverage an SPFM of 90% or higher is required, the results provided in the Safety Analysis Report seem insufficient. 

Can you provide guidance which safety mechanisms described in the Manual can help to increase the SPFM?

    Hi Isabel,

    ASIL-B is a system dependent spec, that being said, with the functional safety manual the system designer might get a system rated ASIL-B, but it won't change the FIT rate of the individual chip. It won't help to increase the SPFM as the transceiver itself is not ASIL-B.

    Regards,
