TC655, TC654 Datasheet - Microchip Technology

TC655 PWM Fan Speed Controller

The TC654 and TC655 are PWM mode fan speed controllers with FanSense technology for use with brushless DC fans. These devices implement temperature proportional fan speed control which lowers acoustic fan noise and increases fan life. The voltage at VIN (Pin 1) represents temperature and is typical.

TC655 Features

* Temperature Proportional Fan Speed for Reduced Acoustic Noise and Longer Fan Life

* FanSense™ Protects against Fan Failure and Eliminates the Need for 3-wire Fans

* Overtemperature Detection (TC655)

* Efficient PWM Fan Drive

* Provides RPM Data

* 2-
