2.2 INA2180-Q1, VSSOP-8 Package

This section provides Functional Safety Failure In Time (FIT) rates for the VSSOP-8 package of INA2180-Q1 based on two different industry-wide used reliability standards:

  • Table 2-5 provides FIT rates based on IEC TR 62380 / ISO 26262 part 11
  • Table 2-6 provides FIT rates based on the Siemens Norm SN 29500-2

Table 2-3 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 6
Die FIT Rate 2
Package FIT Rate 4

The failure rate and mission profile information in Table 2-5 comes from the Reliability data handbook IEC TR 62380 / ISO 26262 part 11:

  • Mission Profile: Automotive Control
  • Power dissipation: 15 mW
  • Climate type: World-wide Table 8
  • Package factor: Lambda 3 Table 17b
  • Substrate Material: FR4
  • EOS FIT rate assumed: 0 FIT

Table 2-4 Component Failure Rates per Siemens Norm SN 29500-2
Table Category Reference FIT Rate Reference Virtual TJ
4 BICMOS Op amp,
comparators, voltage monitors		 8 FIT 45°C

The Reference FIT Rate and Reference Virtual TJ (junction temperature) in Table 2-6 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.
