The LM56 is a precision low power thermostat. 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). The LM56 is available in an 8-lead Mini-SO8 surface mount package and an 8-lead small outline package. This device features digital outputs support TTL logic levels, internal temperature sensor, 2 internal comparators with hysteresis, internal voltage reference, and available in 8-pin SO and Mini-SO8 plastic packages. This device is applicable in wide range application such as in Microprocessor Thermal Management, Appliances, Portable Battery Powered 3.0V or 5V Systems, Fan Control, Industrial Process Control, HVAC Systems, Remote Temperature Sensing, Digital Temperature Sensor and Electronic System Protection.
