Overview

The TB67S580FNG is a bipolar stepping motor driver IC that utilizes a DMOS output stage to deliver up to 1.6A. It supports high-voltage operation up to 44V and features a simple clock-input interface for ease of control without complex SPI programming.

Why Choose This Part

This driver integrates Mixed, Slow, and Fast decay modes to optimize torque and reduce vibration across different speeds. It minimizes external component count by reducing charge pump requirements and provides a 3.3V regulator output to power low-voltage logic or sensors.

Applications

Office Automation
Driving stepper motors in laser printers and multi-function copiers requiring smooth 1/32 micro-stepping.
Industrial Robotics
Precise position control for pick-and-place machines and small-scale robotic actuators.
ATM and Banking Machines
Reliable paper handling and card dispensing mechanisms using the integrated error detection flags.
3D Printers and CNC
Compact motor control for axes and extruders where thermal management and micro-stepping are critical.
