SNVA910A December 2019 – September 2024 LM4128 , LM4128-Q1
The failure mode distribution estimation for the LM4128 and LM4128-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 (%) |
|---|---|
| No OUTPUT (output low) | 30 |
| OUTPUT high (following input) | 20 |
| OUTPUT not in specification | 40 |
| EN false enable | 5 |
| Pin to pin short any two pin | 5 |
