LM57: Example schematic for using two LM57 to provide over and under temperature on / off control to a PSU

Part Number: LM57
Other Parts Discussed in Thread: TMP390

Tool/software:

Please could you provide an example circuit using two LM57 sensors that would provide a single on / off control line to a DC/DC converter.

The DC/DC should power off above +85 degC and also when below -40 degC.

The DC/DC switches on when the control line is above 2.31VDC and off when below 0.99VDC.
