Many electronic circuits related to fan speed controlling have been published here and this one is just another approach. Hi Gerald use thick copper (10 to 20 mm) strips used as link in high current cable links or thick aluminium bars. The Fan Controller without Thermostat makes it simple to manually adjust the running speed of any type of extractor fan.

The load, which is the fan, is connected across the Vout (pin5) and ground (pin3) of the IC. How to make the project and please send the layout the circuit and explanation of the circuit.


I got the required output on breadboard but fail to get output on pcb when layout done on eagle software; I guess I dont know to use the eagle software.
It monitors the temperature of an external NTC thermistor and generates a PWM signal that can be used to control the speed of a 2-, 3-, or 4-wire fan.

The IC has a dropout voltage as low as 0.5 and has also many useful features like power supply reverse protection, thermal protection, short circuit protection etc.
The network comprising of potentiometers R1, R2 and resistor determines adjust current (Iadj) of the IC.
Simply plug the Fan Controller into a power supply and plug your fan into the Fan Controller.


The fan control characteristics are set using external resistors, thereby eliminating the need for an external microcontroller. By varying the Iadj using the POT R2 we can adjust the output voltage of the IC and hence the fan speed. Controllable characteristics include the starting temperature for fan control, PWM frequency, fan speed at low temperatures, and slope of the temperature-duty-cycle transfer function.
