Smarter, Quieter, Safer: Toshiba’s Next‑Generation Stepper Driver Innovation
Advanced microstepping delivers quieter motion, smarter current control, and reliable stall detection:
The TB67S579FTG integrates advanced motor‑control functions to provide smooth, efficient, and reliable stepper‑motor operation. Its Continuous Microstepping Technology enables exceptionally fine current control, greatly reducing noise and vibration during motion. AGC2 automatically adjusts the drive current to match the load, improving power efficiency while maintaining consistent torque, and its built‑in stall detection and anti‑stall behavior allow reliable operation without additional sensors. The device also incorporates AWGS for simple single‑CLK microstepping, along with an integrated charge pump and ACDS architecture that eliminate external capacitors and current‑sense resistors. With ADMD increasing achievable motor speed by up to 30% without adding noise, and a compact VQFN48 package that includes comprehensive protection features, the TB67S579FTG provides a space‑efficient and capable solution for demanding stepper‑motor applications.
