    The TC648 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 the VIN input
    furnishes the required control voltage of 1.25V to 2.65V
    (typical) for 0% to 100% PWM duty cycle. The TC648
    can be configured to operate in either auto-shutdown or
    minimum speed mode. In auto-shutdown mode, fan ...
