Overview

This document contains the Pin failure mode analysis (pin FMA) information for the TLV62095.

Figure 1 shows the device functional block diagram.

Pin Failure Mode Analysis (Pin FMA)

This section provides a failure mode analysis (FMA) for the pins of the TLV62095. The failure modes covered in this document include the typical pin-by-pin failure scenarios:

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

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

Table 2 is showing the TLV62095 pin diagram. For a detailed description of the device pins, see the Pin Configuration and Functions section in the TLV62095 4-A High Efficiency Step Down Converter with DCS-Control Data Sheet.

The exposed thermal pad is connected to AGND.

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

• The device is operating in the typical application, see the Applications section on the first page in the TLV62095 4-A High Efficiency Step Down Converter with DCS-Control Data Sheet.
