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

Table 1-1 Component Failure Rates per IEC TR 62380 / ISO 26262 Part 11

FIT IEC TR 62380 / ISO 26262	FIT (Failures Per 10⁹ Hours), Full Load	FIT (Failures Per 10⁹ Hours), 80% Load
Total Component FIT Rate	24	19
Die FIT Rate	15	11
Package FIT Rate	9	8

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

Table 1-2 Component Failure Rates per Siemens Norm SN 29500-2

Table	Category	Reference FIT Rate	Reference Virtual T_J
5	CMOS, BICMOS Digital, analog /mixed	25 FIT	55°C

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.
