Datasheet Summary
EUM6861/A/B/C
18V PWM Fan Motor Driver
DESCRIPTION
EUM6861/A/B/C is a fan motor driver for the single coil brushless DC motor. With its high efficient direct PWM control mode, EUM6861/A/B/C controls the speed of brushless DC motor with a built in HALL IC interface. EUM6861/A/B/C is suitable to drive variable speed motors for personal puter’s power supply radiation fans and CPU coolers.
EUM6861/A/B/C integrates PWM fan speed control, minimum speed mode, soft start, fan tachometer, lock protection, auto restart and Hall Bias functions. PWM mode controls fan speed in low noise and low vibration ways by adjusting RCTL voltage. EUM6861/A/B/C can set minimum fan speed by presetting RMIN...
