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)
