Table 4-2 Pin FMA for Device Pins Short-Circuited to Ground
Pin Name Pin No. Description of Potential Failure Effects Failure Effect Class
VDD 1 The device is not powered. The device is not functional. Observe that the absolute maximum ratings for all pins of the device are met; otherwise, device damage is plausible. A
DP1 2 The positive remote connection is stuck low. The remote temperature measurement
is out of specification.
B
DN1 3 There is no effect. Operation is normal. D
DP2 4 The positive remote connection is stuck low. The remote temperature measurement
is out of specification.
B
DN2 5 There is no effect. Operation is normal. D
GND 6 There is no effect. Operation is normal. D
T_CRIT 7 T_CRIT is stuck low and is not functional. T_CRIT falsely asserts. B
