Product Summary

The L297/A/D 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
driven in half step, normal and wawe drive modes
and on-chip PWM chopper circuits permit switchmode control of the current in the windings
