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
Applications:
- Personal Computers & Servers
- LCD Projectors
- Datacom & Telecom Equipment
- Fan Trays
- File Servers
- General-Purpose Fan Speed Control
