TC655, TC654, 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
