TC665 - PWM Fan Speed Controllers

Download the TC665 datasheet PDF. This datasheet also covers the TC664 variant, as both devices belong to the same pwm fan speed controllers family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
