TB6600HG

Overview

The TB6600HG is a single-chip bipolar sine wave microstep driver for two-phase stepper motors, manufactured by Toshiba Semiconductor and Storage. It integrates control and power stages using a BiCD 0.13 µm process. The device supports a load voltage range of 8V to 42V with a continuous output current of 4.5A and a peak current of 5.0A. It offers five stepping resolutions: full, half, quarter, eighth, and sixteenth steps. The IC operates within a temperature range of -30°C to +85°C and utilizes a 25-HZIP package.

Feature Summary

• Integrates all functions required to drive two-phase bipolar stepper motors on a single chip, reducing external component requirements.
• Supports multiple excitation modes including 2-phase, 1-2 phase, W1-2 phase, 2W1-2 phase, and 4W1-2 phase for precise motion control.
• Features built-in protection circuits such as thermal shutdown, under-voltage lockout, and over-current detection to ensure reliability.
• Includes an internal oscillator circuit adjustable via an external resistor for precise chopping frequency control.

Applications

• Industrial automation equipment such as conveyor belts and robotic arms
• CNC machines and 3D printers requiring high-precision motor control
• Medical devices like automatic dispensers and imaging equipment
• Consumer electronics including automated curtains and smart home devices

Procurement Notes

Verify the specific suffix designation when ordering, as it may indicate variations in packaging or tape-and-reel configurations rather than functional differences. Confirm the lead time with authorized distributors, as production cycles can extend up to twenty weeks depending on order volume. Ensure compatibility with the target system's voltage and current requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications demanding high torque and smooth operation from bipolar stepper motors. The integrated power MOSFET technology minimizes heat generation compared to older designs. Consider the 25-HZIP package for through-hole mounting needs where space constraints are less critical than in surface-mount alternatives. Evaluate the need for microstepping capabilities to determine if the available resolution options meet the application's precision requirements.
