36V High-Performance High-Reliability Withstand Voltage Stepping Motor Driver
BD63717MUV is a bipolar low-consumption driver that is driven by PWM current. Rated power supply voltage rating of 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 (2 types), HALF STEP mode (2 types), QUARTER STEP mode, 1/8 STEP mode and 1/16 STEP mode via a builtin DAC. Constant current control is possible without using an external sense resistor, and the board area can be reduced. In the method of current decay, the SLOW DECAY or AUTO DECAY can be set. In addition, the power supply can be driven by one single system, which simplifies the design.
