The L297/A/D Stepper Motor Controller IC gener-
　　ates four phase drive signals for two phase bipolar
　　and four phase unipolar step motors in microcom-
　　puter-controlled applications. The motor can be
　　driven in half step, normal and wawe drive modes
　　and on-chip PWM chopper circuits permit switch-
　　mode control of the current in the windings. A
　　feature of this device is that it requires only clock,
　　direction and mode input signals. Since the phase
　　are generated internally the burden on the micro-
　　processor,and theprogrammer, is greatly reduced.
　　Mounted in DIP20 and SO20 packages,the L297
　　can be used with monolithic bridge drives such as
　　the L298N or L293E, or with discrete transistors
