Product Description
- General Description
- The TC642 is a switch mode fan speed controller for use with brushless DC fans. Temperature proportional speed control is accomplished using pulse width mod ulation (PWM). A thermistor (or other voltage output temperature sensor) connected to the VIN input furnishes the required control voltage of 1.25V to 2.65V (typical) for 0% to 100% PWM duty cycle. Minimum fan
- speed is set by a simple resistor divider on the VMIN input. An integrated Start-up Timer ensures reliable motor start-up at turn-on, coming out of shutdown mode or following a transient fault. A logic low applied to VMIN(Pin 3) causes fan shutdown.
- Features
- • Temperature Proportional Fan Speed for Acoustic Control and Longer Fan Life
- • Efficient PWM Fan Drive
- • 3.0V to 5.5V Supply Range:
- - Fan Voltage Independent of TC642 Supply Voltage
- - Supports any Fan Voltage
- • FanSense™Fault Detection Circuits Protect Against Fan Failure and Aid System Testing
- • Shutdown Mode for "Green" Systems
- • Supports Low Cost NTC/PTC Thermistors
- • Space Saving 8-Pin MSOP Package
- • Over-temperature Indication
- Applications
- • Power Supplies
- • Personal Computers
- • File Servers
- • Telecom Equipment
- • UPSs, Power Amps, etc.
- • General Purpose Fan Speed Control
- Available Tools
