Temperature Proportional Fan Speed for Acoustic Control and Longer Fan Life Efficient PWM Fan Drive to 5.5V Supply Range: - Fan Voltage Independent of TC647 Supply Voltage - Supports any Fan Voltage FanSenseTM Technology Fault Detection Circuits Protect Against Fan Failure and Aid System Testing Shutdown Mode for "Green" Systems Supports Low Cost NTC/PTC Thermistors Space Saving 8-Pin MSOP Package
The 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 VIN furnishes the required control voltage to 2.65V (typical) for 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 startup at turn-on, coming out of shutdown mode or following a transient fault. A logic low applied to V MIN (Pin 3) causes fan shutdown. The TC647 also features Microchip Technology's proprietary FanSenseTM 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 shutdown 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.Applications
