BD63520AEFV数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

BD63520AEFV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 (W1-2 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，可对所有电机实现很好的控制状态。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。
