4 Pin Failure Mode Analysis (Pin FMA)

This section provides a Failure Mode Analysis (FMA) for the pins of the ISOW7741-Q1 in 20-DFM package. The failure modes covered in this document include the typical pin-by-pin failure scenarios:

• Pin short-circuited to Ground (see Table 4-2)
• Pin open-circuited (seeTable 4-3)
• Pin short-circuited to an adjacent pin (see Table 4-4)
• Pin short-circuited to supply (see Table 4-5)

Table 4-2 through Table 4-5 also indicate how these pin conditions can affect the device as per the failure effects classification in Table 4-1. Note that when pin short to ground case is discussed, only same side ground shorts are considered.
