4 Pin Failure Mode Analysis (Pin FMA)

This section provides a Failure Mode Analysis (FMA) for the pins of TCAN1051-Q1 and TCAN1051V-Q1 (as well as the TCAN1051H-Q1, TCAN1051G-Q1, TCAN1051HV-Q1, TCAN1051GV-Q1, TCAN1051HG-Q1 and TCAN1051HGV-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 VCC (see Table 4-5)
• Pin short-circuited to VBAT (see Table 4-6)
• Pin short-circuited to VIO (see Table 4-7)

Table 4-2 through Table 4-7 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:

• VCC = 4.5 to 5.5V
• VBAT = 6 to 24V
• VIO = 3 to 5.5V
