33991 SIMPLIFIED APPLICATION DIAGRAM

DESCRIPTION

The 33991 is a Serial Peripheral Interface

(SPI) controlled, dual stepper motor driver IC.

This monolithic IC consists of four dual output

H-Bridge coil drivers and their associated

control and management logic. Each pair of

H-Bridge drivers automatically controls the

speed, direction, and magnitude of current

through the two coils of a two-phase

PWR

instrumentation stepper motor, similar to an

MMT-licensed AFIC 6405.

The GDIC is ideal for use in instrumentation

systems that require distributed and flexible

stepper motor gauge driving. The device

simplifies the use of stepper motors by

including all the logic required to manage the

motion of the stepper without requiring

significant processor overhead. SPI

SCLK

communications are used to request a motor

position and the IC completely manages the

acceleration, stepping, and deceleration of the

motor to arrive correctly at the requested

position. Updated requests can be received at

any time and the logic correctly acts upon the

latest position request. Both motors can be

controlled and driven independently.
