MC642P 数据手册

The MC642 is a pulse width modulation (PWM) fan speed

controller for use with DC motors. It provides temperature

proportional speed control. A thermistor connected to the V_INinput

furnishes the required control voltage of 1.25V to 2.65V for 0% to

100% PWM duty cycle. Minimum fan speed is set by a simple resistor

divider on the V

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 stalled, open, or unconnected fan causes

the MC642 to trigger its start–up timer once. If the fault persists, the

FAULT output goes low, and the device is latched in Shutdown Mode.
