BD63800MUF-C
车载用 40V耐压 低功耗双极PWM恒流驱动 步进电机驱动器
BD63800MUF-C是一款电源额定电压40V、额定输出电流1.35A的低功耗双极PWM恒流驱动的驱动器。输入接口采用CLK-IN驱动方式和SPI-IN驱动方式。励磁模式支持Full step、1/2 step、1/4 step、1/8 step、1/16 step、1/32 step模式。电流衰减方式备有可自由设置Fast decay / Slow decay 比例的Mix decay模式和可自动选择Fast decay / Slow decay的Autodecay模式，可使各种电机实现理想的控制状态。另外，电源也可以用1个系统进行驱动，使配套应用的设计更容易。
