Failure Mode Distribution (FMD)

The failure mode distribution estimation for LMT86-Q1 in Table 2-1 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 judgments.

The failure modes listed in this section reflect random failure events and do not include failures due to misuse or overstress.

Table 2-1 Die Failure Modes and Distribution
Die Failure Modes Failure Mode Distribution (%)
VOUT open (HIZ) 15%
VOUT short to VDD 20%
VOUT short to GND 20%
VOUT not in specification 45%
