SFFS134 November 2022 TIOS1023 , TIOS1025
The failure mode distribution estimation for TIOS102, TIOS1023 and TIOS1025 in Table 3-1 comes from the combination of common failure modes listed in standards such as IEC 61508 and ISO 26262, the ratio of sub-circuit function size and complexity and from best engineering judgment.
The failure modes listed in this section reflect random failure events and do not include failures due to misuse or overstress.
| Die Failure Modes | Failure Mode Distribution (%) (TIOS1023, TIOS125) | Failure Mode Distribution (%) (TIOS102) |
|---|---|---|
| Transmitter failure | 75% | 75% |
| VCC_OUT LDO failure | 6% | Not applicable |
| VCC_IN internal logic failure | Not applicable | 6% |
| NFAULT logic failure | 13% | 13% |
| Control logic failure | 6% | 6% |
