DTC646 - PWM Fan Speed Controller

Description

The TC646 is a switch mode, fan speed controller for use with brushless DC fans.

Temperature proportional speed control is accomplished using pulse width modulation (PWM).

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 TC646 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 Indicatio.
