Stepping Motor Driver  
BD63920MUV  
General Description  
Key Specifications  
BD63920MUV 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 2.0 A.  
CLK-IN and PARA-IN driving mode is adopted for input  
interface, and excitation mode is corresponding to FULL  
STEP mode (2 kinds), HALF STEP mode (3 kinds),  
QUARTER STEP mode (2 kinds), 1/8 step mode and  
1/16 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.
