TC664 - PWM Fan Speed Controllers

Description

The TC664/TC665 devices are PWM mode fan speed controllers with FanSense technology for use with brushless DC fans.

These devices implement temperature proportional fan speed control which lowers acoustic fan noise and increases fan life.

Features

  • 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 Savi.
