TB62218AFTG,C8,EL

Overview

The TB62218AFTG,C8,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS technology to provide fully integrated control and power stages within a 48-VFQFN package. The device operates with a supply voltage range of 4.75V to 5.25V and supports load voltages from 10V to 38V. It delivers an output current of 2A per phase and features four half-bridge outputs. The component supports step resolutions of 1, 1/2, and 1/4 steps via parallel interface. It functions reliably across a junction temperature range of -20°C to +150°C.

Feature Summary

• Fully integrated design combining control logic and power stage in a single chip
• Supports multiple step resolutions including full, half, and quarter stepping modes
• Built-in protection mechanisms for thermal management and overcurrent conditions

Applications

• Bipolar stepper motor control systems
• General purpose motion control applications
• Industrial automation equipment

Procurement Notes

Verify the specific suffix C8,EL against official Toshiba documentation to confirm tape and reel packaging specifications. Confirm RoHS compliance status and Moisture Sensitivity Level (MSL) ratings prior to procurement. Ensure the obsolete part status is accounted for in long-term production planning. Cross-reference the 48-QFN footprint dimensions with PCB layout requirements.

Selection Notes

Select this component for applications requiring high integration of stepper motor driving functions. The DMOS technology offers robust performance for bipolar motors. Evaluate the 2A output current capability against motor coil requirements. Consider the wide operating temperature range for industrial environments. Verify that the parallel interface aligns with the system controller's I/O capabilities.

Part Context

This part belongs to the Toshiba TB622xx series of stepper motor drivers. It is designed for compact applications where space efficiency is critical due to the QFN package. The series typically targets general-purpose motion control needs. Compare with similar models like the TB62214 or TB62213 for variations in current rating or pin configuration.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the TB62213AFTG,C8,EL and TB62214AFTG,C8,EL. Verify electrical compatibility and pinout alignment before substitution. Check if alternative packages are available for the same functional core.
