1 Functional Safety Failure In Time (FIT) Rates

This section provides Functional Safety Failure In Time (FIT) rates for TLIN10283S-Q1 and TLIN10285S-Q1 based on two different industry-wide used reliability standards:

• Table 1-1 provides FIT rates based on IEC TR 62380 / ISO 26262 part 11
• Table 1-2 provides FIT rates based on the Siemens Norm SN 29500-2

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

• Mission Profile: Motor Control from Table 11
• Power dissipation, full load: 500 mW

• Power dissipation, 80% load: 400 mW

• Climate type: World-wide Table 8
• Package factor lambda 3 Table 17b
• Substrate Material: FR4
• Electrical overstress (EOS) FIT rate assumed: 0 FIT

The Reference FIT Rate and Reference Virtual T_J (junction temperature) in Table 1-2 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.
