TB62214AFTG,8,EL

Overview

The TB62214AFTG,8,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It integrates control logic and power stages using DMOS technology within a 48-QFN (7x7 mm) package. The device supports a supply voltage range of 4.75V to 5.25V and handles load voltages from 10V to 38V. It delivers an output current of 2A per phase with four half-bridge outputs. Operating junction temperatures range from -20°C to 150°C. Stepping resolutions include full, half, and quarter steps.

Feature Summary

• Integrates full control logic and power stage in a single DMOS-based IC
• Supports multiple stepping resolutions including full, half, and quarter modes
• Features parallel interface for straightforward digital control

Applications

• General purpose bipolar stepper motor driving
• Motion control systems requiring integrated drive solutions
• Automation equipment utilizing standard stepper motors

Procurement Notes

Verify the specific suffix '8' against official Toshiba documentation to confirm it denotes the correct tape and reel packaging configuration. Ensure the component status is active, as some variants in this series may be obsolete. Cross-reference the 48-QFN pinout with your PCB layout to prevent interface mismatches during integration.

Selection Notes

Select this component when a compact solution for bipolar stepper motors is required. It is suitable for applications needing up to 2A output current with integrated thermal protection. Consider the 48-pin QFN package constraints for thermal dissipation and board space. Verify that the system logic levels are compatible with the parallel interface requirements.

Part Context

This part belongs to the TB62214 family of stepper motor drivers. It shares core functionality with variants like TB62214AFTG,C8,EL but differs in packaging or ordering suffixes. The family utilizes DMOS technology to provide efficient motor control with minimal external components, targeting cost-sensitive and space-constrained industrial applications.

Replacement Considerations

TB62213AFTG,C8,EL and TB62218AFTG,C8,EL are listed as parameter equivalents. Verify pin compatibility and current ratings before substitution. Note that TB62214AFTG,8,EL may have limited availability compared to other suffixes.
