BD63621MUV
36V Stepper Motor Driver

BD63621MUV is a bipolar low-consumption driver that driven by PWM current. Rated power supply voltage of the device is 36V, and rated output current is 2.0A. CLK-IN driving mode is adopted for input interface, and excitation mode is corresponding to FULL STEP mode, HALF STEP mode (2 kinds), 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.
