BD63715AEFV
âGeneral Description
BD63715AEFV 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 1.5 A.
CLK-IN driving mode is adopted for input interface, and
excitation mode is corresponding to FULL STEP mode,
HALF STEP mode (2 types) and QUARTER 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.
