BD63725BEFV

●General Description

● Major Characteristics

BD63725BEFV 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 (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.
