BD63730EFV
36V High-performance, High reliability Withstand Voltage Stepper Motor Driver
BD63730EFV is a low-power motor driver that drives load by PWM current. Rated power supply voltage of the device is 36V, and rated output current is 3.0A. The input interface are interchangeable between CLK-IN drive mode and the PARALLEL-IN drive mode, and excitation mode is corresponding to FULL STEP, HALF STEP (2 types), and QUARTER STEP modes via a built-in DAC. In terms of current decay, the FAST DECAY/SLOW DECAY ratio may be set without any limitation, and all available modes may be controlled in the most appropriate way. In addition, the power supply may be driven by one single system, which simplifies the design.
