TC642B, PWM Fan Speed Controllers
The TC642B/TC647B devices are new versions of the existing TC642/TC647 fan speed controllers.
These devices are switch mode, fan speed controllers that incorporate a new fan auto-restart function.
Temperature-proportional speed control is accomplished using pulse width modulation.
A thermistor (or o
