General Description
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 1.25V to
2.65V (typical) for 0% to 100% PWM duty cycle. The TC646
automatically suspends fan operation when measured temperature (VIN) is below
a user programmed minimum setting (VAS). An integrated Start-up Timer ensures
reliable motor start-up at turn-on, coming out of shutdown mode, auto-shutdown
mode or following a transient fault.
