4 Pin Failure Mode Analysis (Pin FMA)

This section provides a Failure Mode Analysis (FMA) for the pins of the LMR336x0 . The failure modes covered in this document include the typical pin-by-pin failure scenarios:

• Pin short-circuited to Ground (see Table 4-6 and Table 4-6)
• Pin open-circuited (see Table 4-7 and Table 4-7)
• Pin short-circuited to an adjacent pin (see Table 4-8 and Table 4-8)
• Pin short-circuited to VIN (see Table 4-9 and Table 4-9)

Table 4-6 through Table 4-9 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:

• Device used within the Recommended Operating Conditions and the Absolute Maximum Ratings found in the appropriate device data sheet.
• Configuration as shown in the Example Application Circuit found in the appropriate device data sheet.
