[Application] Temperature control circuit
Available in a dual-row SOIC-8 pin package. The working temperature is -40 to 85 °C. The working voltage is 4.5 to 18V. When the voltage is 5 to 18V, the maximum operating current is 200μA, and the output resistance is 400 to 1000Ω.
The characteristic is: the upper limit temperature and the lower limit temperature can be set by the user; when the upper limit temperature is lower than the lower limit temperature, there is a corresponding logic level output, and there is also a control signal output; the control temperature precision can reach ±3 ° C; It can resist static voltage of 2kV; few external components and high reliability. Suitable for thermostats, ovens, fan control and temperature control systems.
