Description

IC PWM FAN SPEED CNTRL 8-SOIC
The TC647 is a switch mode, fan speed controller for use with brushless DC fans. Temperature proportional speed control is accomplished using pulse width mod- ulation (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 set by a simple resistor divider on the VMIN input. An integrated Start-up Timer ensures reliable motor start- up at turn-on, coming out of shutdown mode or following a transient fault. A logic low applied to VMIN (Pin 3) causes fan shutdown. The TC647 also features Microchip Technology's pro- prietary FanSense™ technology for increasing system reliability. 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 TC647 to trigger its Start-up Timer once. If the fault persists, the FAULT output goes low and the device is latched in its shut- down mode. The TC647 is available in the 8-pin plastic DIP, SOIC and MSOP packages and is available in the industrial and extended commercial temperature ranges. 1 8 2 7 3 6 4 5 TC647 GND CF VIN VMIN FAULT SENSE VDD
