The LM56CIM is a precision Thermostat Sensor with two stable temperature trip points (VT1 and VT2) that are generated by dividing down the device 1.250V band-gap voltage reference using 3 external resistors. The device has two digital outputs. OUT1 goes LOW when the temperature exceeds T1 and goes HIGH when the temperature goes below (T1-THYST). Similarly, OUT2 goes LOW when the temperature exceeds T2 and goes HIGH when the temperature goes below (T2-THYST). THYST is an internally set 5°C typical hysteresis.
