BD63715AEFV
36V High-performance, High-reliability Withstand Voltage Stepper Motor Driver

BD63715AEFV is a bipolar low-consumption driver that driven by PWM current. Rated power supply voltage of the device is 36 V, and rated output current is 1.5 A. CLK-IN driving mode is adopted for input interface, and excitation mode is corresponding to FULL STEP mode, HALF STEP mode (2 types) and QUARTER STEP mode 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.

    • Evaluation Board
    • BD63715AEFV-EVK-001
    • This evaluation board is a board for driving the stepping motor with a ROHM's stepping motor driver BD63715AEFV. 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.
