BD68888MUV (New)
36V 2ch Stepping Motor Driver

BD68888MUV 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 1.65 A. PARA-IN drive mode is adopted for input interface. This motor driver can drive 2ch bipolar stepping motors. In addition, the power supply can be driven by one single system, which siplifies the design.
