SFFS609 February 2025 TPS35
The failure mode distribution estimation for TPS35 and TPS36 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 (%) |
|---|---|
False assert on RESET or WDO | 1% |
RESET or WDO remain asserted | 3% |
| Incorrect timing operation (early or late WDO faults, RESET/WDO de-assertion delays) | 66% |
| RESET trip outside of specification. | 24% |
Supply current is out of spec | 6% |
