BD63716AMWV

General Description

Key Specifications

BD63716AMWV 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 the method of current decay, the

FAST DECAY/SLOW DECAY ratio can set without any

limitation, and all available modes can be controlled in the

most appropriate way. In addition, the power supply can

be driven by one single system, which simplifies the

design.
