TB62218AFG,C8,EL

Overview

The TB62218AFG,C8,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS parallel technology to integrate control and power stages within a single package. The device supports full, half, and quarter step resolutions for precise motion control. Key electrical parameters include a maximum output current of 3A per phase, a load voltage range of 10V to 38V, and a supply voltage of 4.75V to 5.25V. It operates within a junction temperature range of -20°C to 150°C and features an HSOP-28 surface-mount package.

Feature Summary

• Integrates full control logic and power output stages for simplified system design
• Supports selectable stepping modes including full, half, and quarter steps
• Incorporates built-in protection mechanisms against overcurrent and thermal overload

Applications

• Office automation equipment such as printers and copiers
• Industrial positioning systems and CNC machinery
• Security systems requiring precise actuator control

Procurement Notes

Verify the specific suffix C8,EL to confirm the tape and reel packaging configuration and RoHS compliance status. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements. Cross-reference the datasheet revision date to confirm compatibility with existing design specifications before finalizing procurement.

Selection Notes

Select this component when a high-current bipolar stepper driver is required in a compact surface-mount form factor. The integrated DMOS architecture reduces external component count compared to discrete solutions. Evaluate thermal management requirements based on the 1.15W power dissipation rating and the thermal characteristics of the HSOP-28 package for the specific application environment.
