![]() And provides all the necessary drive signals for the power stage. ![]() This IC accepts the control signals from the system’s controller, usually a microcomputer chip. Or with discrete transistors and darlingtons in stepper motor driving applications. ![]() The L297 Stepper Motor Controller primarily intended for use with an L298N or L293E bridge driver. L297 Stepper Motor Controller IC easily mounted in DIP20 and SO20 packages. As the phase generated internally the load on the microprocessor, and the programmer, reduced greatly. This device requires only clock, direction and mode input signals. And also the two on-chip PWM chopper circuits permit switch-mode control of the current in the windings. This motor has the capacity to drive in half step, normal and wawe drive modes. The L297 Stepper Motor Controller IC designed with four phase drive signals for two phase bipolar and four phase unipolar step motors in microcomputer-controlled applications.
