This section provides Functional Safety Failure In Time (FIT) rates for TPSM365R1x based on two different industry-wide used reliability standards:

• Table 2-3 provides FIT rates based on IEC TR 62380 / ISO 26262 part 11
• Table 2-4 provides FIT rates based on the Siemens Norm SN 29500-2

The failure rate and mission profile information in Table 2-3 comes from the Reliability data handbook IEC TR 62380 / ISO 26262 part 11:

• Mission Profile: Motor Control from Table 11
• Power dissipation: 140 mW
• Climate type: World-wide Table 8
• Package factor (lambda 3): Table 17b
• Substrate Material: FR4
• EOS FIT rate assumed: 0 FIT

The Reference FIT Rate and Reference Virtual T_J (junction temperature) in Table 2-4 come from the Siemens Norm SN 29500-2 tables 1 through 5. Failure rates under operating conditions are calculated from the reference failure rate and virtual junction temperature using conversion information in SN 29500-2 section 4.
