Features & Applications

The TC646BEOA is a part of TC646 Series PWM Controller.It can sustain a standard temperature ranging from -40 to +85 °C it comes in 8 pin SOIC package.

The TC646B is a new version of the existing TC646 fan speed controller. This device is a switch mode fan speed controller, which incorporates a new fan auto restart function. Temperature proportional speed control is accomplished using pulse width modulation.

Features:

  • Temperature-Proportional Fan Speed for Acoustic Noise Reduction and Longer Fan Life
  • Efficient PWM Fan Drive
  • 3.0 V to 5.5 V Supply Range:
  • Fan Voltage Independent of TC646B/TC648B/TC649B Supply Voltage
  • Supports any Fan Voltage
  • FanSense™ Fault Detection Circuit Protects Against Fan Failure and Aids System Testing (TC646B/TC649B)
  • Automatic Shutdown Mode for “Green” Systems
  • Supports Low Cost NTC/PTC Thermistors
  • Over-Temperature Indication (TC646B/TC648B)
  • Fan Auto-Restart
  • Space-Saving 8-Pin MSOP Package
