PC33991 GAUGE DRIVER INTEGRATED CIRCUIT
This GDIC 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, direc-
tion and magnitude of current through the two coils of a 2-phase instrumentation stepper
motor, similar to an MMT-licensed AFIC 6405.
A special patent-pending circuit detects motor stall accurately and allows simple end stop
detection.
The GDIC is ideal for use in instrumentation systems which 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 communications are
used to request a motor position
and the IC completely manages the
acceleration, stepping and deceler-
ation of the motor to arrive correct-
ly 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.
