• Manufacturer Part Number: mlx90320
• Description: Automotive Smart Sensor Interface Ic
• Manufacturer: Melexis Company

When a short-circuit of FLT with VDD occurs the output goes to the high fault band. For all other internal faults
the output goes to the low fault band.
External faults
Short-circuit
In all of these above mentioned fault cases, the IC will generate an output within either of the diagnostic bands.
Open circuit
In case of open circuit the output will go to the high fault band.
The MLX90320 must survive to the following reversed contacts but the output does not go to the fault bands.
