The TC664 is a single PWM mode fan speed controller with FanSense™ TM technology for use with brushless DC motors. The device allows temperature proportional speed control and therefore accomplishes lower acoustic fan noise and longer fan life. The TC664 reads the voltage provided by an external thermistor (or voltage output temperature sensor) and adjusts a 30% to 100% PWM duty cycle output to the fan with respect to the input temperature voltage. The PWM duty cycle can also be programmed via SMBus to allow fan speed control without the need of an external thermistor. In normal fan operation, pulse trains are present at the SENSE pin. These pulses are used to calculate the fan RPM.
