Standard SPI™ and STEP/DIR interfaces simplify communication. Integrated power MOSFETs handle motor currents up to 2A per coil. Integrated protection and diagnostic features support robust and reliable operation. High integration, high energy efficiency and small form factor enable miniaturized designs with low external component count for cost-effective and highly competitive solutions. Universal, cost-effective stepper drivers for two-phase bipolar motors with state-of-the-art features. Integrated MOSFETs for up to 2 A motor currents per coil. With Step/Dir Interface and SPI. |
