4 Pin Failure Mode Analysis (Pin FMA)

This section provides a Failure Mode Analysis (FMA) for the pins of the TPS3710-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)
• Pin open-circuited (see Table 4-3)
• Pin short-circuited to an adjacent pin (see Table 4-4)
• Pin short-circuited to VDD (see Table 4-5)

Table 4-2 through Table 4-5 also indicate how these pin conditions can affect the device as per the failure effects classification in Table 4-1.

Figure 4-1 shows the TPS3710-Q1 pin diagram. For a detailed description of the device pins please refer to the Pin Configuration and Functions section in the TPS3710-Q1 data sheet.

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

• Unless otherwise specified, it is assumed that the voltages applied to all the pins are within the Recommended Operating Range specified in the TPS3710-Q1 data sheet.
• Note that the SENSE pin has lower maximum operating range than VDD and OUT.
• For shorts to VDD, this document assumes the SENSE pin maximum is not exceeded.
• Refer to Typical Application Circuit diagram in the datasheet for test layout.
