TC642 - PWM Fan Speed Controller

TC642 Description

M .
The TC642 is a switch mode fan speed controller for use with brushless DC fans.

TC642 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 F

TC642 Applications
