SFFSAJ9A June 2025 – September 2025 UCC27289
The failure mode distribution estimation for UCC27289 in Table 3-2 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 (%) |
|---|---|
| HO stuck high | 16.5 |
| HO stuck low | 16.5 |
| HO voltage out of specified range | 16.5 |
| LO stuck high | 16.5 |
| LO stuck low | 16.5 |
| LO voltage out of specified range | 16.5 |
| UVLO not functional | 1 |
