SFFS612 May 2025 TPS748A-Q1
The failure mode distribution estimation for the TPS748A-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 (%) |
|---|---|
| OUT no output (GND) | 35 |
| OUT high (following input) | 10 |
| OUT not in specification voltage or timing | 45 |
| PG false trip, fails to trip | 5 |
| Short circuit any two pins | 5 |
