SFFS597 april 2023 TPS7B85-Q1
The failure mode distribution estimation for the TPS7B85-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) | 40 |
VOUT low (no output) | 40 |
Short any two pins | 10 |
VOUT not in specification (voltage or timing) | 5 |
PG false trigger, fails to trigger | 5 |
