36V Stepping Motor Driver
BD68610EFV
âGeneral Description
BD68610EFV is a bipolar low-consumption driver that
driven by PWM current. Rated power supply voltage of
the device is 36 V, and rated output current is 1.0A.
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.
