STEPPER MOTOR CONTROLLERS

L297 L297D STEPPER MOTOR CONTROLLERS NORMAL/WAWE DRIVE HALF/FULL STEP MODES CLOCKWISE/ANTICLOCKWISE DIRECTION SWITCHMODE LOAD CURRENT REGULA- TION PROGRAMMABLE LOAD CURRENT FEW EXTERNAL COMPONENTS RESET INPUT & HOME OUTPUT ENABLE INPUT DESCRIPTION The L297/A/D Stepper Motor Controller IC gener- ates four phase drive signals for two phase bipolar and four phase unipolar step motors in microcom- puter-controlled applications. The motor can be driven in half step, normal and wawe drive modes and on-chip PWM chopper circuits permit switch- mode control of the current in the windings. A August 1996 Symbol Parameter Value Unit V s Supply voltage 10 V V i Input signals 7V P tot Total power dissipation (T amb =70°C) 1 W T stg ,T j Storage and junction temperature -40 to + 150 °C ABSOLUTE MAXIMUM RATINGS feature of this device is that it requires only clock, direction and mode input signals. Since the phase are generated internally the burden on the micro- processor,and theprogrammer,is greatly
