Stepper Motor Driver Controller TB67S109AFTG

Overview

Input signal is isolated via a high-speed optocoupler and stationary current is automatically reduced by half. It is suitable for any small / medium automatic equipment with CNC controller, such as X-Y-Z tables, labeling machines, laser cutters, engraving machines, and pick-place devices.

H-bridge bipolar constant phase flow driver
The maximum output current is 4.0A (eight optional)
Up to 32 segments of six kinds of sub-modes available
The input signal high-speed photoelectric isolatio
Standard common anode single pulse interface
Offline keep function
Semi-enclosed chassis can adapt to a more demanding environment
Provide energy saving semiautomatic current lock function
Built-in thermal protection and over-current protection
