TB67S149FTG,EL

Overview

The TB67S149FTG,EL is a unipolar stepper motor driver manufactured by Toshiba Semiconductor and Storage. It features an integrated power MOSFET architecture with two half-bridge outputs capable of delivering up to 3A output current. The device supports a load voltage range of 10V to 40V and operates on a 5V logic supply (4.75V to 5.25V). It accommodates step resolutions from full step to 1/32 microstepping. Packaged in a 48-WQFN (7x7) surface-mount format, it functions within a temperature range of -20°C to +85°C.

Feature Summary

• Integrates control logic and power stages into a single monolithic circuit for simplified design.
• Supports high-resolution microstepping up to 1/32 steps per quadrant for smooth motion control.
• Utilizes parallel interface for straightforward connection to standard microcontrollers.

Applications

• Unipolar stepper motor control systems
• General-purpose industrial automation equipment
• Motion control applications requiring precise positioning

Procurement Notes

Verify the specific suffix EL against official Toshiba documentation to confirm tape-and-reel packaging configuration. Ensure the ordering quantity aligns with manufacturer minimum order requirements. Cross-reference the RoHS compliance status directly with the latest datasheet revision to meet environmental regulations. Confirm thermal dissipation capabilities match the target application's power constraints before finalizing procurement.

Selection Notes

Select this component when driving unipolar stepper motors requiring up to 3A continuous current. It is suitable for applications needing microstepping resolution up to 1/32. Consider the 48-WQFN package for compact board layouts. Verify that the system load voltage does not exceed the 40V maximum rating. Evaluate thermal management needs based on the specified power dissipation limits.
