4 Pin Failure Mode Analysis (Pin FMA)

This section provides a failure mode analysis (FMA) for the pins of the DRV81602-Q1 and for the device variations DRV81242-Q1, DRV81620-Q1, and DRV81080-Q1. The failure modes covered in this document include the typical pin-by-pin failure scenarios:

• Pin short-circuited to ground (see Table 4-14, Table 4-14, Table 4-14, and Table 4-14)
• Pin open-circuited (see Table 4-15, Table 4-15, Table 4-15, and Table 4-15)
• Pin short-circuited to an adjacent pin (see Table 4-16, Table 4-16, Table 4-16, and Table 4-16)
• Pin short-circuited to supply (see Table 4-17, Table 4-17, Table 4-17, and Table 4-17)

Table 4-14 through Table 4-17 also indicate how these pin conditions can affect the device as per the failure effects classification in Table 4-1.

Following are the assumptions of use and the device configuration assumed for the pin FMA in this section:

• The device is used with external components consistent with the values described in the external component table of the datasheet.
