μ-step适用36V耐压 步进电机驱动器系列_BD63521EFV

BD63521EFV是适用于1/16µ-step的步进电机驱动器。作为基本功能,是低功耗双极PWM恒流驱动器,额定电源为36V、额定输出电流(DC)为2.0A,接口为CLK-IN驱动型。通过内置DAC,励磁模式适用于Full step (2相励磁)、Half step (1-2相励磁)、Quarter step (2W1-2 相励磁)、Sixteenth step (4W1-2相励磁)模式,对于电流衰减方式,可自由设定FAST DECAY/SLOW DECAY的比率,可对所有电机实现最佳控制状态。另外,也可使用一个系统电源进行驱动,因此有助于提高整机设计的便利性。
