SFFS504 March 2023 TPS7A16-Q1
The failure mode distribution estimation for the TPS7A16-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 (%) |
|---|---|
| VOUT high (following VIN) | 35 |
| VOUT not in specification | 15 |
| VOUT low (no output) | 35 |
| PG false trigger, fails to trigger | 10 |
| Short circuit any two pins | 5 |
