BD63521EFV
μ-step适用36V耐压 步进电机驱动器系列
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。

- Evaluation Board - BD63521EFV-EVK-001
This evaluation board is a board for driving the stepping motor with a ROHM's stepping motor driver BD63521EFV. Motor drive and driver The motor can be driven by VCC for power supply and 5V power supply for control signal. Drive / stop and excitation modes can be set with an external switch. The input interface adopts the CLK-IN drive system, and the excitation mode supports FULL STEP, HALF STEP, QUATER STEP, 1/8 STEP, and 1/16 STEP mode by the built-in DAC.
