4 Pin Failure Mode Analysis (Pin FMA)

This section provides a Failure Mode Analysis (FMA) for the pins of the TPS3760-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 supply (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.

Table 4-1 shows the TPS3760-Q1 pin diagram. For a detailed description of the device pins please refer to TPS3760-Q1 in the Pin Configuration and Functions section of the data sheet.

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

• RESET are pictured as active low, some configurations (RESET) will be active low. RESET in Figure 4-1 is shown as open-drain, some configurations will be push-pull. Refer to TPS3760-Q1 Pin Configuration and Functions section of the data sheet.
• At V_{DD (MIN)} ≤ VDD ≤ V_{DD (MAX)}, CTR = CTS = Open
• Output reset Pullup Resistor (R_PULLUP) = 10 kΩ, Output reset pullup voltage (V_PULLUP = 5.5 V, output reset load (C_LOAD) = 10 pF.
• Tables valid over the operating free-air temperature range of – 40°C to 125°C, unless otherwise noted.
• Typical values are at T_A = 25°C, VDD = 16 V, and V_IT = 6.5 V (V_IT refers to V_ITN or V_ITP) unless stated otherwise.
