BD63725BEFV
高性能、高可靠性36V耐压 步进电机驱动器
BD63725BEFV是额定电源36V?额定输出电流2.5A的低功耗双极PWM恒流驱动器。输入接口采用CLK-IN驱动方式，通过内置DAC，励磁模式可适用于FULL STEP?HALF STEP(2种)?QUATER STEP模式。电流衰减方式方面可任意设定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，有助于提高整机设计的便利性。

- Evaluation Board - BD63725BEFV-EVK-001
This evaluation board is a board for driving the stepping motor with a ROHM's stepping motor driver BD63725BEFV. 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.
