General Description  
• Shutdown Mode for "Green" Systems  
• Supports Low Cost NTC/PTC Thermistors  
• Space Saving 8-Pin MSOP Package  
• Over-temperature Indication  
The TC646 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 the V input fur-  
IN  
Applications  
• Power Supplies  
• Computers  
• File Servers  
• Portable Computers  
Telecom Equipment  
• UPS, Power Amps  
• General Purpose Fan Speed Control  
nishes the required control voltage of 1.25V to 2.65V  
(typical) for 0% to 100% PWM duty cycle. The TC646  
automatically suspends fan operation when measured  
temperature (V ) is below a user programmed  
IN  
minimum setting (V ). An integrated Start-up Timer  
AS  
ensures reliable motor start-up at turn-on, coming out  
of shutdown mode, auto-shutdown mode or following a  
transient fault.  
The TC646 features Microchip Technology's propri-  
etary 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 TC646 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. FAULT is also asserted if the PWM  
reaches 100% duty cycle, indicating a possible thermal  
runaway situation, although the fan continues to run.  
See Section 5.0, “Typical Applications”, for more  
information and system design guidelines.  
Available Tools  
• Fan Controller Demonstration Board (TC642DEMO)  
• Fan Controller Evaluation Kit (TC642EV)  
The TC646 is available in the 8-pin plastic DIP, SOIC  
and MSOP packages and is available in the industrial  
and extended commercial temperature ranges.
