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
driven in half step, normal and wawe drive modes
and on-chip PWM chopper circuits permit switchmode
control of the current in the windings.
Features:
- NORMAL/WAWE DRIVE
- HALF/FULL STEP MODES
- CLOCKWISE/ANTICLOCKWISEDIRECTION
- SWITCHMODE LOAD CURRENT REGULATION
- PROGRAMMABLE LOAD CURRENT
- FEW EXTERNALCOMPONENTS
- RESET INPUT & HOME OUTPUT
- ENABLE INPUT
- 20-pin DIP
