SFFS855 December 2024 LMR60430-Q1 , LMR60440 , LMR60440-Q1
The failure mode distribution estimation for the LMR60430, LMR60430-Q1, LMR60440, and LMR60440-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 resulting from misuse or overstress.
| Die Failure Modes | Failure Mode Distribution (%) |
|---|---|
| No output voltage | 60 |
| Output voltage not in specification - voltage or timing | 30 |
| Gate driver stuck on | 5 |
| Power good false trip or failure to trip | 5 |
