SFFS049 March 2021 TPS61379-Q1
The failure mode distribution estimation for TPS61379-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 due to misuse or overstress.
| Die Failure Modes | Failure Mode Distribution (%) |
|---|---|
| VO No output GND or HiZ | 50% |
| VO output not in specification voltage or timing | 40% |
| Load disconnect stuck on | 5% |
| PG false trip, fails to trip | 5% |
