TB6600HG Parameter Description

The TB6600HG is a high-power, PWM chopper-type two-phase bipolar stepping motor driver IC engineered by Toshiba. Capable of driving a forward- and reverse-rotation control system, this monolithic integrated circuit delivers micro-step driving with a built-in clock decoder. It is specifically optimized for high-torque industrial applications, supporting an operating voltage range of up to 50V and a maximum output current of 4.5A. To withstand substantial thermal loads during peak operation, the IC is housed in a rugged, heat-sink-ready 25-pin ZIP power package (HZIP25-P-1.00F). This combination makes it a definitive choice for automated machinery requiring precise positioning and high electrical reliability.


Technical Highlights & Architectural Merits


* High Output Power Threshold: Supports a maximum absolute output voltage rating of 50V and continuous output current execution up to 4.5A, allowing direct control of large NEMA 23 and NEMA 34 stepper motors.

* Selectable Micro-step Resolution: Features integrated excitation modes allowing full-step, half-step, 1/4-step, 1/8-step, and 1/16-step resolutions for exceptionally smooth motor rotation and precise position control.

* On-Chip Protective Guardrails: Outfitted with automatic thermal shutdown (TSD) circuits, overcurrent protection (ISD), and under-voltage lockout (UVLO) mechanics to minimize system failures under harsh operational spikes.

* Single-Chip Bipolar Chopper Configuration: Utilizes an efficient BiCD silicon process that combines bipolar, CMOS, and DMOS technologies to minimize heat dissipation while maintaining massive current routing efficiency.


Typical Applications


* CNC Machinery & 3D Printers: Providing high-current phase driving for linear axes, heavy-duty gantries, and professional engraving machines.

* Industrial Robotics & Automation: Serving as the core positioning driver for multi-axis robotic arms, pick-and-place conveyor modules, and sorting equipment.

* Textile & Printing Equipment: Ensuring precise, repeatable fabric and paper feed indexing control under high-speed continuous assembly operations.
