TB67S142FTG,EL

Overview

The TB67S142FTG,EL is a fully integrated unipolar stepper motor driver manufactured by Toshiba Semiconductor and Storage. It utilizes power MOSFET technology to deliver an output current of 3A with a load voltage range of 10V to 40V. The device operates on a supply voltage of 4.75V to 5.25V and supports step resolutions of 1, 1/2, and 1/4. Housed in a 48-WQFN (7x7) package with an exposed pad, it functions within an ambient temperature range of -20°C to 85°C.

Feature Summary

• Integrates control logic and power stages for unipolar stepper motors
• Supports selectable step resolutions including full, half, and quarter steps
• Utilizes parallel interface for direct connection to microcontrollers

Applications

• Industrial printers
• Numerical control machine tools
• General purpose automation systems

Procurement Notes

Verify the specific suffix EL against official Toshiba documentation to confirm tape and reel packaging requirements. Confirm that the 48-WQFN package dimensions match your PCB footprint design. Ensure thermal management strategies account for the exposed pad requirement during integration.

Selection Notes

Select this component when driving unipolar stepper motors requiring up to 3A continuous current. It is suitable for applications needing 1, 1/2, or 1/4 step resolution control via a parallel interface. Verify that the system load voltage remains within the 10V to 40V operational window.

Part Context

This part belongs to the Toshiba TB67S series of stepping motor driver ICs. These devices are designed as complete solutions for controlling stepper motors in industrial environments. The series typically features robust protection mechanisms and high integration levels to simplify system design.

Replacement Considerations

The TB67S142NG and TB67S142HG are alternative packages within the same electrical specification family. Verify pin compatibility and thermal performance before substituting surface mount variants with through-hole options.
