XL297 – Stepper Motor Controller – Xinluda

The Xinluda XL297 is a stepper motor controller IC in an SOP-20 package that generates four-phase drive signals for two-phase bipolar and four-phase unipolar stepper motors, with an on-chip PWM chopper for switch-mode winding-current control.

The XL297 from Xinluda is a stepper motor controller IC designed to generate four-phase drive signals for two-phase bipolar and four-phase unipolar (single-pole) stepper motors in microcomputer-controlled systems. The device handles motor phase-sequence generation on-chip, reducing the load on the host microprocessor: the system needs to supply only clock, direction, and mode signals. This makes it a practical building block for compact, low-overhead stepper drive designs. The XL297 follows the well-known L297-class controller architecture, and a companion device, the XD297, offers the same function in a DIP20 package.

The device drives the motor in normal (two-phase-on), wave (one-phase-on), and half-step modes. Its integrated dual PWM chopper circuit enables switch-mode control of the winding current, with the peak current programmed by a reference voltage on the V_ref pin. The XL297 is intended to pair with a dual bridge driver such as the XZ298N, a quad Darlington array, or discrete power devices, giving designers flexibility across a range of motor sizes and current levels.
