36V 2ch Stepper Motor Driver - BD63888AEKV

BD63888AEKV is a bipolar low-consumption driver that driven by PWM constant current. Rated power supply voltage of the device is 36 V, and rated output current is 1.5 A. CLK-IN drive mode is adopted for input interface, and excitation mode is corresponding to FULL STEP mode, HALF STEP mode (2 types) and QUARTER STEP mode via a built-in DAC. The power supply can be driven by one single system, which simplifies the design.

* This is STANDARD grade product. For on-vehicle usage, please contact Sales.
