PWM Temperature Controlled FAN using TC648 and NTC sensor

https://www.electronics-lab.com/pwm-temperature-controlled-fan-using-tc648-and-ntc-sensor/

The project described here is a switch mode fan speed controller for use with brushed or brushless DC motors. Temperature proportional speed control is accomplished using pulse width modulation (PWM). 10K Ohms NTC is used to sense the temperature. The project is built using TC648 chip and configured with auto-shutdown mode. In Auto-Shutdown mode, fan […]
