Features and Applications

The TC664EUN is a part of TC664 Series PWM Controllers . It can sustain a temperature ranging from -40°C to +85°C. It comes in 10 pin MSOP package.

The TC664 is a single PWM mode fan speed controller with FanSense™ technology for use with brush-less DC motors. The device allows temperature proportional speed control and therefore accomplishes lower acoustic fan noise and longer fan life. 


  • Temperature Proportional Fan Speed for Reduced Acoustic Noise and Longer Fan Life
  • FanSense™ Protects against Fan Failure and Eliminates the Need for 3-wire Fans
  • Over Temperature Detection (TC665)
  • Efficient PWM Fan Drive
  • Provides RPM Data
  • 2-Wire SMBus™-Compatible Interface
  • Supports Any Fan Voltage
  • Software Controlled Shutdown Mode for "Green" Systems
  • Supports Low Cost NTC/PTC Thermistors
  • Space Saving 10-Pin MSOP Package
  • Temperature Range: -40°C to +85ºC
