Thermistor is a semiconductor device made of materials whose resistance varies as a function of temperature. A thermistor can be used to compensate for temperature variation in other components of an ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

The ZXBM1004 pre-driver IC offers flexible, variable-speed control of single-phase brushless DC fans and blowers. The device is compatible with NTC thermistor, voltage and pulse-width modulated (PWM) ...
