L297 L297D STEPPER MOTOR CONTROLLERS NORMAL/WAWE DRIVE HALF/FULL STEP MODES CLOCKWISE/ANTICLOCKWISE DIRECTION SWITCHMODE LOAD CURRENT REGULATION PROGRAMMABLE LOAD CURRENT FEW EXTERNAL COMPONENTS RESET INPUT & HOME OUTPUT ENABLE INPUT DESCRIPTION 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-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 temperature Parameter Value 10 7 1 -40 to + 150 Unit V V W °C DIP20 SO20 ORDERING NUMBERS : L297 (DIP20) L297D (SO20) 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 micropr [ … ]
