General Description
The TC642 is a switch mode fan speed controller for use with brushless DC
fans. Temperature proportional speed control is accomplished using pulse width
mod ulation (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. Minimum fan
speed is set by a simple resistor divider on the VMIN input. An integrated
Start-up Timer ensures reliable motor start-up at turn-on, coming out of
shutdown mode or following a transient fault. A logic low applied to VMIN(Pin
3) causes fan shutdown.
