SNOAA49A December 2019 – April 2024 LM4050-N-Q1
The failure mode distribution estimation for the LM4050-N-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 (%) |
|---|---|
| VR voltage accuracy outside of the specifications | 40 |
| VR does not meet dynamic impedance specification | 20 |
| Minimum regulation current exceeds maximum value of the specification | 40 |
