SMD258C Two-Phase Hybrid Stepper Motor Driver, Resolution up to 40000S/R Overview

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.

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 Supports alerts for undervoltage, overvoltage, overheat, overcurrent Supports phase memory when power down Optical isolation for both I/O signal and input signal When the stepping pulse stops over 100ms, coil current will be halved automatically Comes with development resources and manual (examples for Raspberry Pi, STM32, Arduino) Specifications Operating voltage: DC 24V ~ 80V Signal voltage: 4.2V ~ 24V Drive current: 0.5A ~ 5A Signal frequency: ≤150KHz Control mode: common cathode, common anode, and differential Applications

The SMD258C is suit for medium or small size CNC equipments which requires high resolution, such as:
