TC646, PWM Fan Speed Controller
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
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
