3 Failure Mode Distribution (FMD)

The failure mode distribution estimation for the INA241x-Q1 and INA296x-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.

Table 3-1 Die Failure Modes and Distribution

Die Failure Modes	Failure Mode Distribution (%)
Output open (Hi-Z)	10
Output to GND	30
Output to VS	30
Output functional, not in specification	10
Pin to pin short, any two pins	20
