Micro step 36V Stepper Motor Drivers
BD63521EFV is stepper motor drivers of 1/16 micro step (sixteenth step) drive. As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supply rated voltage of 36V and rated output current (DC) of 2.0A. The input interface is CLK-IN type. It's step modes of Full step & Half step, Eighth step, Sixteenth step mode by internal DAC (D-A converter), and for current decay mode, the ratio of FAST DECAY & SLOW DECAY can be freely set, so the optimum control conditions for every motor can be realized. In addition, being able to drive with one system of power supply makes contribution to the set design’s getting easy.

Reference Design / Application Evaluation Kit
-
- Evaluation Board - BD63521EFV-EVK-001
This evaluation board is a board for driving the stepping motor with a ROHM's stepping motor driver BD63521EFV. 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.
