TB67S539FTG(O,EL)

Overview

The TB67S539FTG(O,EL) is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It features an integrated control and power stage with NMOS technology. The device supports step resolutions of 1, 1/2, 1/4, 1/8, 1/16, and 1/32 micro-step modes. It operates with a supply voltage range of 6V to 34V for the load and requires a 6V logic supply. The output current capability is rated at 2A. The component utilizes a PWM interface and offers a half-bridge configuration with four outputs. It is housed in a 32-VQFN (5x5) package with a bare pad for surface mount installation.

Feature Summary

• Integrates full control and power stages for simplified circuit design
• Supports multiple micro-step resolutions from full step to 1/32 micro-step
• Utilizes NMOS technology for efficient power management
• Features a compact 32-VQFN package with exposed pad for thermal performance

Applications

• General purpose stepper motor control systems
• Precision positioning applications requiring micro-stepping
• Industrial automation equipment
• Office automation devices

Procurement Notes

Verify the specific suffix designation matches the required packaging option, as variations exist between cut tape, reel, and other handling formats. Confirm that the 32-VQFN footprint aligns with the target PCB layout, paying attention to the exposed thermal pad requirements for adequate heat dissipation during operation. Ensure the input signal levels are compatible with the specified logic supply voltage range before integration into the final system design.

Selection Notes

Select this component when a single-chip solution for bipolar stepper motors is required with support for high-resolution micro-stepping up to 1/32. It is suitable for applications demanding a 2A output current within a 34V maximum load voltage limit. Consider the 32-VQFN package constraints if space is limited, and ensure the design accommodates the necessary thermal management for the exposed pad configuration under continuous load conditions.

Part Context

This part belongs to Toshiba's series of stepping motor driver ICs designed for general use. It represents a class of integrated solutions that combine logic control with power switching elements. The TB67S539 variant specifically targets applications needing precise motion control with reduced component count compared to discrete driver implementations.
