EUM6804 PWM Fan Motor Driver with Slope Control and Low Duty Startup DESCRIPTION EUM6804 is a fan motor driver for brushless DC fan motor. It integrates three types speed control modes, low duty startup function, soft switched output, lock protection, Hall bias, FG output, shutdown mode, quick restart and TSD. With these modes and functions, EUM6804 can not only be applied to DC fans which require different speed curves, but also be applied to NB and other portable equipments which require silence and low power dissipation. The three types speed control modes are PWM control mode, VCC control mode with slope adjustable, normal VCC control mode. Low duty startup function makes it possible for DC fan to start and restart under a very low PWM duty cycle.
