36V Stepping Motor Driver

BD68620EFV

●General Description

●Major Characteristics

BD68620EFV 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 2.0A.

PALA-IN driving mode is adopted for input interface. 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.
