L297D STEPPER MOTOR CONTROLLERS

L297D Description

L297 L297D STEPPER MOTOR CONTROLLERS NORMAL/WAWE DRIVE HALF/FULL STEP MODES CLOCKWISE/ANTICLOCKWISE DIRECTION SWITCHMODE LOAD CURRENT REGULATION PROGR.
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.

L297D 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. A ABSOLUTE MAXIMUM RATINGS Symbol Vs Vi Ptot Tstg, Tj Supply voltage Input signals Total power dissipation (Tamb = 70°C) Storage and junction
