BD63731EFV

General Description

Key Specifications

BD63731EFV is a bipolar low-consumption driver that is

driven by PWM current. Rated power supply voltage of

the device is 36 V, and rated output current is 3.0 A.

CLK-IN driving mode is adopted for input interface, and

excitation mode is corresponding to FULL STEP mode (2

types), HALF STEP mode (2 types), QUARTER STEP

mode (2 types), 1/8 STEP mode and 1/16 STEP mode

via a built-in DAC. In terms of current decay, the SLOW

DECAY/FAST 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.
