36V High-performance and High-reliability Withstand Voltage Stepping Motor Driver - BD63730EFV

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.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
