MLX90320
Automotive small sensor interface
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
• Output with VDD
• Output with GND
• Output with Vbat
In all of these above mentioned fault cases, the IC will generate an output within either of the diagnostic bands.
Open circuit
• VDD open
• GND open
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.
• Reverse polarity
• Reverse battery polarity
• Output reversed with GND
• Output reversed with VDD
