2 Functional Safety Failure In Time (FIT) Rates

This section provides Functional Safety Failure In Time (FIT) rates for TPS4811x-Q1 based on industry-wide used reliability standard:

• Table 2-1 provides FIT rates based on IEC TR 62380 / ISO 26262 part 11

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
• Power dissipation: 27 mW
• Climate type: World-wide Table 8 IEC TR 62380
• Package factor (lambda 3): Table 17b IEC TR 62380
• Substrate Material: FR4
• EOS FIT rate assumed: 0 FIT
