illustrate

The LM56 is a high-precision, low-power thermostat. Two stable temperature jump points (V T1 and V T2) are divided by the 3 external resistors to generate the lower LM56 1.250V bandgap reference voltage. The LM56 has two digital outputs. OUT1 becomes low, and when the temperature exceeds T1 and becomes higher, the temperature is lower (T1 - T HYST). Similarly, OUT2 becomes low, when the temperature exceeds T2 and becomes high, when the temperature falls below (T2 - T HYST). T HYST is internally set 5°C typical hysteresis.

The LM56 is available in an 8-pin small SO8 surface mount package and an 8-pin small form factor package.
