3 Functional Safety Failure In Time (FIT) Rates

This section provides Functional Safety Failure In Time (FIT) rates for the LMR54410 and LMR54406 based on the following industry-wide used reliability standards:

  • Table 3-1 provides FIT rates based on IEC TR 62380 / ISO 26262 part 11

Table 3-1 Component Failure Rates per IEC TR 62380 / ISO 26262 Part 11
FIT IEC TR 62380 / ISO 26262 FIT (Failures Per 109 Hours)
Total Component FIT Rate 13
Die FIT Rate 10
Package FIT Rate 3

The failure rate and mission profile information in Table 3-1 comes from the Reliability data handbook IEC TR 62380 / ISO 26262 part 11:

  • Mission Profile: Motor Control from Table 11
  • Power dissipation: 250 mW
  • Climate type: World-wide Table 8
  • Package factor (lambda 3): Table 17b
  • Substrate Material: FR4
  • EOS FIT rate assumed: 0 FIT
