SFFS013A December 2020 – July 2021 TPS37-Q1 , TPS38-Q1
The failure mode distribution estimation for TPS37-Q1 and TPS38-Q1 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 (%) |
|---|---|
| RESET1_XXXX / fails to trip | 8% |
| RESET1_XXXX / false trip | 8% |
| RESET1_XXXX / trip outside specification (voltage or time) | 31% |
| RESET1_XXXX / delay outside specification | 3% |
| RESET2_XXOD / fails to trip | 8% |
| RESET2_XXOD / false trip | 8% |
| RESET2_XXOD / trip outside specification (voltage or time) | 31% |
| RESET2_XXOD / delay outside specification | 3% |
