Stepper Motor Control/Driver


The L293D is a monolithic integrated, high voltage, high current, 4-channel driver.

  • L293E is a quad push-pull driver capable of delivering output currents up to 1A per channel
  • L297 generates four phase drive signals for two phase bipolar and four phase unipolar stepper motors in microcomputer controlled applications

L293DAccepts DTL/TTL logic levels, will drive inductive loads, DC and stepper DIL-1682-0192
motors, switching power transistors.
L293ETTL compatible control, inhibit input on each pair of drivers, external DIL-2082-0194
connections for sensing resistors.
L297Motor can be driven in half-step, normal and wave drive modes, on-chip DIL-2082-0198
PWM chopper circuits permit switch-mode control of the current in the
windings. Requires only clock, direction and mode input signals.
