TB67S128FTG(O,EL)

Overview

The TB67S128FTG(O,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 parallel interface input with output currents up to 5A per phase. It operates with a load voltage range of 6.5V to 44V and a supply voltage of 0V to 5.5V. The component features selectable step resolutions including 1/8, 1/16, and 1/32 steps. It is housed in a 64-VQFN (9x9mm) package with exposed pads for thermal dissipation.

Feature Summary

Integrates full control logic and power stages for bipolar stepper motors
Supports multiple micro-stepping resolutions via parallel interface
Utilizes power MOSFET technology for high current drive capability

Applications

General purpose stepper motor control systems
Industrial automation equipment requiring precise positioning
Office automation devices such as printers and scanners

Procurement Notes

Verify the specific suffix designation when ordering, as variations exist between TB67S128FTG and TB67S128FTG(O,EL). Confirm that the required packaging format matches availability from authorized distributors. Ensure the application design accounts for the thermal requirements of the 64-VQFN package given the 5A output capability.

Selection Notes

Select this component for applications requiring high current drive for bipolar stepper motors with integrated control. It is suitable where space constraints favor a compact QFN package over discrete solutions. Consider the parallel interface requirement for control signals and ensure the system voltage aligns with the specified load and supply ranges.

Part Context
