PWM Fan Speed Controller with Auto-Shutdown and FanSense??Technology

General Description The TC646 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 requ
