The values of LM56 Thermostat project Circuit diagram of R1, R2 and R3 for the points of travel, VT1 and VT2 can be determined using the subsequent equations. This thermostat of electronic circuit with IC LM56 diagram what simple project, you can use as reference. As you know, IC LM56 is correct double output thermostat low power characterized by

National Semiconductors. trip temperature stable 2 points called VT1 and VT2 are made with dividing the LM56 IC 1, 250 reference internal voltage volts by three outside resistors (R1, R2 and R3) component. There are 2 digital outputs for LM56 IC which is that output1 becomes weak when the temperature increases over T1 and goes high when the temperature decreases below (temperature T1 ±Hysteresis). Component IC LM56 has a variety of useful features as internal voltage reference internal temperature sensor, 2 internal voltage comparators, etc.
