The MAX31740 is a sophisticated, yet easy-to-use fan-speed controller. 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 ...
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) ...
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 ...
