This document contains information for TIOS102(x) family of devices (TIOS102, TIOS1023 and TIOS1025) to aid in a functional safety system design. Infomation provided are:
Figure 1-1 and Figure 1-2 show the device functional block diagrams for reference.
The devices were developed using a quality-managed development process, but was not developed in accordance with the IEC 61508 or ISO 26262 standards.
This section provides Functional Safety Failure In Time (FIT) rates for TIOS102(x) based on two different industry-wide used reliability standards:
FIT IEC TR 62380 / ISO 26262 | FIT (Failures Per 109 Hours) DRC-10 (VSON Package) |
---|---|
Total Component FIT Rate | 9 |
Die FIT Rate | 5 |
Package FIT Rate | 4 |
The failure rate and mission profile information in Table 2-1 comes from the Reliability data handbook IEC TR 62380 / ISO 26262 part 11:
FIT IEC TR 62380 / ISO 26262 | FIT (Failures Per 109 Hours) DRC-10 (VSON Package) |
---|---|
Total Component FIT Rate | 7 |
Die FIT Rate | 3 |
Package FIT Rate | 4 |
The failure rate and mission profile information in Table 2-2 comes from the Reliability data handbook IEC TR 62380 / ISO 26262 part 11:
Table | Category | Reference FIT Rate | Reference Virtual TJ |
---|---|---|---|
5 | BICMOS, ASIC, Analog & Mixed ≤ 50 V Supply | 25 FIT | 55°C |
The Reference FIT Rate and Reference Virtual TJ (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.
