L297 Stepper motor CONTROLLERSNORMAL/WAVE DRIVEHALF/FULL STEP MODESCLOCKWISE/ANTICLOCKWISE DIRECTIONSWITCHMODE LOAD CURRENT REGULA-TIONPROGRAMMABLE LOAD CURRENTFEW EXTERNAL COMPONENTSRESET INPUT & HOME OUTPUTENABLE INPUTDESCRIPTIONThe L297 Stepper motor Controller IC generatesfour phase drive signals for two phase bipolar andfour phase unipolar step motors in microcomputer-controlled applications. The motor can be driven inhalf step, normal and wawe drive modes and on-chip PWM chopper circuits permit switch-modecontrol of the current in the windings.

Since the phase are gen-erated internally the burden on the microprocessor,and the programmer, is greatly reduced.
