LM56CIM Description

    The LM56 is a precision low power thermostat. Two stable temperature trip points (VT1 and VT2) are generated by dividing down the LM56 1.250V bandgap voltage reference using 3 external resistors. The LM56 has two digital outputs. OUT1 goes LOW when the temperature exceeds T1 and goes HIGH when the 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.

    The LM56 is available in an 8-lead Mini-SO8 surface mount package and an 8-lead small outline package.
