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.

TC642B Features

* Temperature-Proportional Fan Speed for Acoustic Noise Reduction and Longer Fan Life

* Efficient PWM Fan Drive

* 3.0V to 5.5V Supply Range: - Fan Voltage Independent of TC642B/TC647B Supply Voltage - Supports any Fan Voltage

* FanSense™ Fault Detection Circuit Protec
