SFFSA77 January 2025 DRV81008-Q1
The failure mode distribution estimation for the DRV81008-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 (%) |
|---|---|
| OUT is stuck LOW when commanded OFF | 10 |
| OUT is stuck OFF when commanded LOW | 10 |
| OUT ON resistance too high when commanded LOW | 10 |
| OUT slew rate too fast or too slow | 10 |
| OUT is stuck HIGH when commanded OFF | 10 |
| OUT is stuck OFF when commanded HIGH | 10 |
| OUT ON resistance too high when commanded HIGH | 9 |
| Incorrect fault indication | 25 |
| Incorrect operation of clamp circuit | 6 |
