TB67S265FTG,EL

Overview

The TB67S265FTG,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It integrates control logic and power MOSFETs in a single package. The device supports full-step and half-step driving modes with an output current capacity of 2 A per phase. It operates within a load voltage range of 10 V to 47 V and accepts a supply voltage between 4.75 V and 5.25 V. The component utilizes parallel or serial interfaces for command input. It is housed in a 48-WQFN (7x7 mm) surface-mount package with exposed thermal pads.

Feature Summary

• Integrates full-bridge driver circuits with internal control logic for simplified system design
• Supports both parallel and serial interface options for flexible microcontroller connection
• Includes built-in protection mechanisms against overcurrent, overheating, and under-voltage lockout

Applications

• Office automation equipment such as printers and copiers
• Industrial positioning systems requiring precise motion control
• Automotive interior actuation modules

Procurement Notes

Verify the specific suffix EL indicates the reel packaging configuration when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management requirements align with the WQFN-48 package specifications for sustained operation at rated currents.

Selection Notes

Select this component for applications requiring integrated bipolar stepper motor control without external logic gates. The 2 A output rating suits moderate torque requirements. Verify interface compatibility with the host controller's available pins, as the device supports both serial and parallel modes. Consider thermal dissipation capabilities given the 1.3 W power dissipation rating in the specified package.

Part Context

This part belongs to Toshiba's TB67S series of stepping motor drivers designed for compact, high-performance motion control solutions. The series emphasizes integration by combining power stages and control functions. The TB67S265 variant specifically targets bipolar stepper motors with higher current demands compared to lower-end models in the same family.

Replacement Considerations

TB67S269FTG,EL offers similar functionality but with a reduced output current rating of 1.4 A. TB67S261FTG,EL provides comparable bipolar drive capabilities with identical current specifications. Cross-referencing pinouts and thermal characteristics is required before substitution.
