SFFS232A September 2021 – July 2022 TLV3601 , TLV3602

2.1 DCK, DBV, DGK, DSG Packages

This section provides Functional Safety Failure In Time (FIT) rates for the DCK and DBV packages of TLV3601 and DGK and DSG packages of TLV3602 based on two different industry-wide used reliability standards:

Table 2-1 provides FIT rates based on IEC TR 62380 / ISO 26262 part 11
Table 2-3 provides FIT rates based on the Siemens Norm SN 29500-2

Table 2-1 TLV3601 Component Failure Rates per IEC TR 62380 / ISO 26262 Part 11

FIT IEC TR 62380 / ISO 26262	DCK FIT (Failures Per 10⁹ Hours)	DBV FIT (Failures Per 10⁹ Hours)
Total Component FIT Rate	3	4
Die FIT Rate	2	2
Package FIT Rate	1	2

Table 2-2 TLV3602 Component Failure Rates per IEC TR 62380 / ISO 26262 Part 11

FIT IEC TR 62380 / ISO 26262	DGK FIT (Failures Per 10⁹ Hours)	DSG FIT (Failures Per 10⁹ Hours)
Total Component FIT Rate	7	4
Die FIT Rate	3	2
Package FIT Rate	4	2

The failure rate and mission profile information in Table 2-1 comes from the Reliability data handbook IEC TR 62380 / ISO 26262 part 11:

Mission Profile: Motor Control from Table 11
TLV3601 Power dissipation: 19.8 mW
TLV3602 Power dissipation: 39.6 mW
Climate type: World-wide Table 8
Package factor (lambda 3): Table 17b
Substrate Material: FR4
EOS FIT rate assumed: 0 FIT

Table 2-3 TLV3601, TLV3602 Component Failure Rates per Siemens Norm SN 29500-2

Table	Category	Reference FIT Rate	Reference Virtual T_J
4	CMOS, BICMOS Digital, analog / mixed	12 FIT	55°C

The Reference FIT Rate and Reference Virtual T_J (junction temperature) in Table 2-3 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.
