4 Pin Failure Mode Analysis (Pin FMA)

This section provides a Failure Mode Analysis (FMA) for the pins of the TPS7B82-Q1 (DGN, DRV, and KVU packages). The failure modes covered in this document include the typical pin-by-pin failure scenarios:

• Pin short-circuited to Ground (see Table 4-2, Table 4-6 and Table 4-10.)
• Pin open-circuited (see Table 4-3, Table 4-7 and Table 4-11)
• Pin short-circuited to an adjacent pin (see Table 4-4, Table 4-8 and Table 4-12)
• Pin short-circuited to VBAT (see Table 4-5, Table 4-9 and Table 4-13)

Table 4-2 through Table 4-13 also indicate how these pin conditions can affect the device as per the failure effects classification in Table 4-1.
