SFFS775 February 2025 LM74912-Q1
The failure mode distribution estimation for LM74912-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 (%) |
|---|---|
| DGATE output functional, not in specification voltage or timing | 13 |
| DGATE stuck at high | 10 |
| DGATE stuck at low | 14 |
| HGATE output functional, not in specification voltage or timing | 8 |
| HGATE stuck at high | 4 |
| HGATE stuck at low | 16 |
| Short circuit protection fails to trip or false trip | 6 |
| SLEEP switch stuck off | 8 |
| SLEEP switch stuck on | 8 |
| UVLO, OV fails to trip or false trip | 8 |
| Pin to pin short | 5 |
