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) ...

This post is a peek into the Beta and Steinhart-Hart equations for representing the resistance vs. temperature relationship in NTC thermistors. As defined by IEC 60539, NTC (Negative Temperature ...
