Product Summary

The LM56BIM is a Dual Output Low Power Thermostat. The LM56BIM is a precision low power thermostat. Two stable temperature trip points (VT1 and VT2) are generated by dividing down the LM56BIM 1.250V bandgap voltage reference using 3 external resistors. The LM56BIM 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℃ typical hysteresis. The LM56BIM is available in an 8-lead Mini-SO8 surface mount package and an 8-lead small outline package. The applications of the LM56BIM 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.
