TB67S289FTG,EL

Overview

The TB67S289FTG,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It supports clock-controlled operation for 2-phase motors with an output current of 3A and a load voltage range of 10V to 47V. The device operates within a temperature range of -20°C to +85°C and features a 48-VQFN package. It includes built-in microstep decoding, advanced mixed decay mode (ADMD), and active gain control (AGC) to prevent stalling.

Feature Summary

• Built-in CLK-In decoder for microstep driving via input clock signals
• Advanced Mixed Decay Mode (ADMD) for fast and accurate current tracking
• Active Gain Control (AGC) technology prevents motor stalling during operation

Applications

• Clock-controlled 2-phase bipolar stepper motor systems
• Applications requiring microstep drive capabilities
• Systems needing integrated stall prevention mechanisms

Procurement Notes

Verify the specific suffix EL against official Toshiba documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with 48-VQFN footprint requirements in your PCB layout. Confirm that the 3A continuous output rating aligns with your thermal management design constraints.

Selection Notes

Select this component when a clock-driven interface is required for precise stepper motor positioning. The integrated AGC feature makes it suitable for applications where load variations might cause instability. Consider the 48-pin QFN package size relative to available board space and thermal dissipation needs.

Part Context

This part belongs to the TB67S2xx series of stepping motor driver ICs. These devices utilize BiCD process technology to support high-voltage operation and large current driving. The series offers various current ratings while maintaining identical pin assignments for easy interchangeability within the family.

Replacement Considerations

TB67S279FTG,EL and TB67S249FTG,EL are confirmed substitutes within the same family. They share identical pin configurations but differ in output current capacity and overcurrent detection thresholds. Verify that the alternative's current rating meets your motor's requirements.
