It is switch-mode fan speed controller that incorporates a new fan auto-restart function. Temperature-proportional speed control is accomplished using pulse width modulation. A thermistor connected to the VIN input supplies the required control voltage of 1.2 to 2.6V typical for 0 to 100% PWM duty cycle. The auto-shutdown threshold\/temperature is set by a simple resistor divider on the VAS input. An integrated Start-Up Timer ensures reliable fan motor start-up at turn-ON, coming out of shutdown mode, auto-shutdown mode or following a transient fault. A logic low applied to VIN causes fan shutdown. In normal fan operation, a pulse train is present at SENSE. A missing-pulse detector monitors this pin during fan operation. A stalled, open or unconnected fan causes this device to turn the VOUT output on full. If the fan fault persists, the FAULT output goes low.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTemperature proportional fan speed for acoustic noise reduction and longer fan life\u003c\/li\u003e\n\u003cli\u003eEfficient PWM fan drive\u003c\/li\u003e\n\u003cli\u003eFanSense™ Fault detection circuit protects against fan failure and aids system testing\u003c\/li\u003e\n\u003cli\u003eAutomatic shutdown mode for green systems\u003c\/li\u003e\n\u003cli\u003eSupports NTC\/PTC thermistors\u003c\/li\u003e\n\u003cli\u003eFan auto-restart\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eComputers \u0026amp; Computer Peripherals, Consumer Electronics, Communications \u0026amp; Networking, HVAC\u003c\/p\u003e\n\u003ch3\u003eWarnings\u003c\/h3\u003e\n\u003cp\u003eMarket demand for this product has caused an extension in leadtimes.
