DESCRIPTION

The GS-D200 and the GS-D200S are drive mod-

ules that directly interface a microprocessor to a two

phase, bipolar, permanent magnet stepper motors.

The phase current is chopper controlled, and the

internal phase sequence generation reduces the

burden of the controller and it simplifies software

development.

The GS-D200 uses bipolar power outputs while the

GS-D200S has powermos outputs to significantly

reduce both commutation and conduction losses.

A further benefit offered by the GS-D200S is the

complete protection of the outputs against any type

of shorts.
