1 Pin Failure Mode Analysis (Pin FMA)

This section provides a failure mode analysis (FMA) for the pins of the TPS62402-Q1. The failure modes covered in this document include the typical pin-by-pin failure scenarios:

• Pin short-circuited to ground (see Table 1-2)
• Pin open-circuited (see Table 1-3)
• Pin short-circuited to an adjacent pin (see Table 1-4)
• Pin short-circuited to supply (see Table 1-5)

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

Figure 1-1 shows the TPS62402-Q1 pin diagram. For a detailed description of the device pins, see the Pin Configuration and Functions section in the TPS62402-Q1 data sheet.

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

• Assumption the device is running in the typical application, please refer to the 'Simplified Schematic' on the first page in the TPS62402-Q1 data sheet.
