ROHM BD68620EFV-E2, Stepper Motor Stepper Motor Controller IC 24-Pin, HTSSOP

BD68620EFV is a bipolar low-consumption driver that driven by PWM current. Rated power supply voltage of the device is 36V, and rated output current is 2.0A. PALA-IN driving mode is adopted for input interface. In terms of current decay, the FAST DECAY/SLOW DECAY ratio may be set without any limitation, and all available modes may be controlled in the most appropriate way. In addition, the power supply may be driven by one single system, which simplifies the design.
