All 3 stepper motors feature half and full step sequences.

LSI/CSI (Melville, NY) announces the availability of 3 new high performance stepper motor controller ICs. Designated LS8297, LS8297CT and LS8397, these ICs can replace the expensive L297 in all applications, while providing additional features not available in L297. All 3 feature: 

• Pin-for-pin cost effective replacement for L29.
• Half and full step sequences.
• Normal-drive/wave-drive.
• Torque ripple correction in LS8297CT.
• PWM chopper circuit for motor current control.
• Inputs for step, forward/reverse, reset and output blanking control.
• Supply current < 400uA.
• Supply voltage: 4.5V to 7V.
