Micro step 36V Stepper Motor Drivers - BD63525AEFV

BD63525AEFV series are 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 2.5A. The input interface is CLK-IN type. There are step modes of Full step & Half step, Quarter 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.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
