Hi,
I am looking for a temperature sensor IC with the following specifications:
- Automotive grade
- Output voltage linearly proportional to Celcius
- Sensing range of -40 to 125 Degrees Celcius
- DC offset to allow measurement of negative temperature without the need of negative supply
- wide supply range
- Very low self heating when encapsulated in potting epoxy
- Small package size
- (IMPORTANT) Have a dedicated probe pin for measuring temperature of a pad. This pad should not be electrically connected in any way; it should act as heat transfer only.
The device should handle current (80A) and voltage (100V) spikes in its vicinity (not directly connected to sensor).

I have looked at the following as well:
TC1047A (does not have a heat transfer pin. Other than that is has very good specs)
MCP9701A (not sure if the NC pins in the 5 pin package are heat transfer pins)

Thanks,
