36V 2ch Stepper Motor Driver - BD68888AEKV (New)

BD68888AEKV 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. PARA-IN drive mode is adopted for input interface. This motor driver can drive 2ch bipolar stepper motors. In addition, the power supply can be driven by one single system, which simplifies the design.

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