SFFS549 April 2024 LM7481-Q1
The failure mode distribution estimation for LM7481-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 (%) |
|---|---|
| DGATE output stuck at Low | 30% |
| HGATE output stuck at Low | 25% |
| DGATE output not in specification – voltage or timing | 15% |
| HGATE output not in specification – voltage or timing | 15% |
| DGATE output stuck at High | 5% |
| HGATE output stuck at High | 5% |
Short circuit any two pins | 5% |
