The TC647 is a switch mode, fan speed controller for
use with brushless DC fans. Temperature proportional
speed control is accomplished using pulse width modulation (PWM). A thermistor (or other voltage output
temperature sensor) connected to VIN furnishes the
required control voltage of 1.25V to 2.65V (typical) for
0% to 100% PWM duty cycle. Minimum fan speed is …
