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

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
