2 Pin Failure Mode Analysis (Pin FMA)

This section provides a failure mode analysis (FMA) for the pins of the TPSM8282x. The failure modes covered in this document include the typical pin-by-pin failure scenarios:

• Pin short-circuited to ground (see Table 2-2)
• Pin open-circuited (see Table 2-3)
• Pin short-circuited to an adjacent pin (see Table 2-4)
• Pin short-circuited to VIN (see Table 2-5)

Table 2-2 through Table 2-5 also indicate how these pin conditions can affect the device as per the failure effects classification in Table 2-1.

Figure 2-1 shows the TPSM8282x pin diagram. For a detailed description of the device pins, see the Pin Configuration and Functions section in the TPSM8282x data sheet.
