BD63730EFV
General Description
BD63730EFV is a low-power motor driver that drives
load by PWM current. Rated power supply voltage of
the device is 36V, and rated output current is 3.0A. The
input interface are interchangeable between CLK-IN
drive mode and the PARALLEL-IN drive mode, and
excitation mode is corresponding to FULL STEP, HALF
STEP (2 types), and QUARTER STEP modes via a
built-in DAC. 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.
