Intelligent temperature controller MAX6641 circuit diagram
As shown in the figure, it uses PWMOUT terminal to drive N channel MOSFET, then to control the fan speed. remote PN junction temperature sensor can be replaced by the emitter junction of microprocessor (μP) internal temperature measurement triode. It also can adopt discrete component triode such as CMPT3906、T3906、KST3906-TF、SMBT3906 and other models. On the conditions of the highest prospective temperature and 10μA current, it requires the forward voltage drop of triode emitter junction should be higher than 0.25V ; on the conditions of the lowest prospective temperature and 100μA current, it should be lower than 0.95V. It should not use high power triode. (View)
