SFFS541A May 2023 – August 2024 AFE78201 , AFE88201
The failure mode distribution estimation for the AFE78201 and AFE88201 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 (%) |
|---|---|
| DAC output incorrect or not functional | 44 |
| Digital communication error | 23 |
| Diagnostic ADC measurement incorrect or not functional | 20 |
| Reset at power-on and internal supplies not functional | 9 |
| Internal oscillator not functional | 4 |
