ST Stepper Motor Control/ Driver
- ST L297/1, The L297 Stepper motor controller IC generates four phase drive signals for two phase bipolar & four phase unipolar step motors in microcomputer controlled applications. The motor can be driven in half step, normal & wave drive modes & 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 & mode input signals. L297/1 Stepper Motor Controller
