When DS1620 is used to supervise the microprocessor temperature, by opening or closing the fan, the radiation condition can be changed, so the temperature control can be done, see as the figure. Its feature is that TCOM signal controls the fan by 2N7000 MOSFET, when the temperature of the chip surface is higher than tH, the fan is turning on, and the state will last till t
