L297D controllers equivalent, stepper motor controllers.
The motor can be driven in half step, normal and wawe drive modes and on-chip PWM chopper circuits permit switchmode co.
The L297/A/D 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-c.
