l297 stepper motor controller circuits

Four appearance drive signals for two appearance bipolar and four appearance unipolar footfall motors in microcomputer-controlled appliance is calmly implemented application L29 Stepper Motor Controller IC. We can drive the motor in bisected step, accustomed and beachcomber drives approach and switch-mode ascendancy of the accepted in the windings

is permuted on dent PWM chopper circuits. This accessory has some appearance like it requires alone clock, administration and approach ascribe signals. Since the appearance are produced internally the accountability on the microprocessor, and the programmer, is decidedly reduced. This accessory is army in DIP20 and SO20 packages. We can use L297 with caked arch drives such as L293E or L298N, or we additionally can use it with detached transistors and Darlingtons.
