Description:

Fan speed controller.

TC648, Fan Speed Controller

The TC648 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

TC648 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 TC648 Supply Voltage - Supports any Fan Voltage

* Over-temperature Fault Detection

* Automatic Shu
