TC649BEOATR Products

The TC649BEOATR is a switch mode fan speed controller for use with brushless DC motors. 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.The TC649BEOATR automatically suspends fan operation when measured temperature (VIN) is below a user-programmed minimum setting (VAS). An integrated Start-Up Timer ensures reliable motor start-up at turn-on, coming out of Shutdown Mode, or following a transient fault.In normal fan operation, a pulse train is present at SENSE, Pin 5. A Missing-pulse Detector monitors this pin during fan operation. A stalled, open, or unconnected fan causes the TC649BEOATR to trigger its Start-up timer once. If the fault persists, the FAULT output goes low, and the device is latched in its Shutdown Mode. See the Applications section for more information and system design guidelines.The TC649BEOATR is packaged in a space-saving 8-Pin PDIP, MSOP or a SOIC package and is available in the industrial temperature range.
