Description: ELM331 Solid State Thermostat Descriptio n The ELM331 is a complete temperature measurement and control system in an 8 pin package. This integrated circuit is designed to compare two resistances an d drive an output pin depending on the relative value of each. Typically, one of the resistors will be an NTC thermis tor, and the other one will be a temper ature independent resistor (whether fix ed or variable). When the magnitude of the resistance connected to pin 2 excee ds the value of the resistance connecte d to pin 3, the output pin will be driv en to a high state. Hysteresis maintain s www.DataSheet4U.com the output in tha t state until the relative values diffe r by approximately 8% (or typically
