Control of the motor
The stepper motor can rotate in either direction according
to the sequence of the input signals. It is possible to obtain
a full step, a half step and quarter step operation.
Full step operation
Both windings of the stepper motor are energized all the
time with the same current I
MA
= I
MB
.
IN0 and IN1 remain fixed at whatever torque value is
required.
Calling A the condition with winding A energized in one
direction and A in the other direction, the sequence for
full step rotation is:
AB

The application diagram shows a typical application in
which two CS3717A's control a two phase bipolar stepper
motor.
Programming
The amplitude of the current flowing in the motor wind-
ing is controlled by the logic inputs IN0 and IN1. The
truth table (page 3) shows three current levels and an off
state. A high level on the òDirectionó logic input sets the
direction of that current from OUTA to OUTB; a low level
from OUTB to OUTA.
It is recommended that unused inputs are tied to V
CC
or
(Gnd) as appropriate to avoid noise problems.
The current levels can be varied continuously by changing
V
REF
.
