SLLA525A October 2020 – April 2021 TCAN1043-Q1 , TCAN1043G-Q1 , TCAN1043H-Q1 , TCAN1043HG-Q1
The failure mode distribution estimation for TCAN1043-Q1 (as well as TCAN1043G-Q1, TCAN1043H-Q1, and TCAN1043HG-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 due to misuse or overstress.
| Die Failure Modes | Failure Mode Distribution (%) |
|---|---|
| Receiver fail | 35% |
| Transmitter fail | 35% |
| System stuck in sleep mode | 15% |
| CANL or CANH driver biased dominant indefinitely | 5% |
| Short-circuit of any two pins | 5% |
| Reports erroneous fault condition | 5% |
