36VHigh-performance,
High-reliability Withstand Voltage
Stepping Motor Driver
BD63524EFV
General Description
BD63524EFV 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 2.5 A.
CLK-IN driving mode is adopted for input interface, and
excitation mode is corresponding to FULL STEP mode,
HALF STEP mode, QUARTER STEP mode and 1/8
STEP mode 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.
