STMicroelectronics L297 Stepper Motor Controller Datasheet
The L297 is a stepper motor controller IC designed for microcomputer-controlled applications. It generates four-phase drive signals for both bipolar and unipolar step motors, supporting normal, wave, and half-step drive modes. The device features on-chip PWM chopper circuits for switch-mode current control and requires only clock, direction, and mode input signals, reducing the burden on the microprocessor.
