1.2 Functional Safety Failure In Time (FIT) Rates

This section provides Functional Safety Failure In Time (FIT) rates for TLC6C5716-Q1 based on two different industry-wide used reliability standards:

#GUID-932CFAE1-9536-4520-9EC4-A06585204F17/TABLE21 provides FIT rates based on IEC TR 62380 / ISO 26262 part 11
#GUID-932CFAE1-9536-4520-9EC4-A06585204F17/TABLE22 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)
Total Component FIT Rate	39
Die FIT Rate	5
Package FIT Rate	34

The failure rate and mission profile information in #GUID-932CFAE1-9536-4520-9EC4-A06585204F17/TABLE21 comes from the Reliability data handbook IEC TR 62380 / ISO 26262 part 11:

Mission Profile: Motor Control from Table 11
Power dissipation: 1000 mW
Climate type: World-wide Table 8
Package factor (lambda 3): Table 17b
Substrate Material: FR4
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 ASICs Analog & Mixed=<50V supply	60 FIT	70°C

The Reference FIT Rate and Reference Virtual T_J (junction temperature) in #GUID-932CFAE1-9536-4520-9EC4-A06585204F17/TABLE22 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.
