Product Summary

The LM56CIMX is a precision low power thermostat. Two stable temperature trip points (VT1 and VT2) are generated by dividing down the LM56CIMX 1.250V bandgap voltage reference using 3 external resistors. The LM56CIMX 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). The applications of the LM56CIMX include Microprocessor Thermal Management, Appliances, Portable Battery Powered 3.0V or 5V Systems, Fan Control, Industrial Process Control, HVAC Systems, Remote Temperature Sensing, Electronic System Protection.
