APPLICATION INFORMATION
TWO PHASE BIPOLAR STEPPER MOTOR CONTROL CIRCUIT
This circuit drives bipolar stepper motors with winding currents up to 2A. The diodes are fast ... INPUT
DESCRIPTION
The L297 Stepper Motor Controller IC generates
four phase drive signals for two phase bipolar and
four phase unipolar step motors in microcomputer-
controlled applications. The motor can be ... such as the
L298N or L293E, or with discrete transistors and
darlingtons.
