Temprature control circuit using Three -wire serial interface with intelligent temperature sensor DS1620

With the DS1620 monitors the temperature of the microprocessor , through open or close the fan , can change the chip ‘s thermal conditions , to achieve constant temperature control circuit as shown. It features the TCOM signal through the 2N7000 type MOSFET, to control the fan , when the chip surface temperature t> tH open when the fan , and has been maintained.
