TC646

PWM Fan Speed Controller

TC646 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 F

TC646 General 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). A thermistor (or other voltage output temperature sensor) connected to the VIN input furnishes the required control voltage of 1.
