SMD258C Two-Phase Hybrid Stepper Motor Driver

SMD258C Two-Phase Hybrid Stepper Motor Driver

The SMD258C is a two-phase motor driver for hybrid stepper motors, supports 16 grades setting for both drive current and stepping subdivision, resolution up to 40000S/R. It is widely used in CNC equipment, sculpturing machine, cutting machine, etc.

User Manual / Datasheet / Example Codes Etc.

Features

• Wide range voltage input (DC 24V~80V)
• 16 grades stepping subdivision setting, resolution up to 40000S/R
• 16 grades drive current setting, adjustable between 0.5A/Phase and 5.0A/Phase
• Supports three control modes: common cathode, common anode, and differential
