4 Pin Failure Mode Analysis (Pin FMA)

This section provides a Failure Mode Analysis (FMA) for the pins of the DRV8889-Q1 and DRV8889A-Q1. The failure modes covered in this document include the typical pin-by-pin failure scenarios:

• Pin short-circuited to Ground (see Table 4-2 for HTSSOP package, see Table 4-6 for QFN package)
• Pin open-circuited (see Table 4-3 for HTSSOP package, see Table 4-7 for QFN package)
• Pin short-circuited to an adjacent pin (see Table 4-4 for HTSSOP package, see Table 4-8 for QFN package)
• Pin short-circuited to supply (see Table 4-5 for HTSSOP package, see Table 4-9 for QFN package)

Table 4-2 through Table 4-9 also indicate how these pin conditions can affect the device as per the failure effects classification in Table 4-1.
