Overview
The TB62218AFG,8,EL is a bipolar stepper motor driver manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS technology and features a parallel interface for control signals. The device operates with a supply voltage range of 4.75V to 5.25V and supports load voltages from 10V to 38V. It provides an output current capability of 3A per channel. The component is housed in a 28-HSOP package with two thermal pads and is rated for junction temperatures between -20°C and 150°C.
Feature Summary
- Integrates full control logic and power stages for bipolar stepper motors
- Supports multiple step resolutions including full, half, and quarter steps
- Utilizes DMOS technology for efficient power switching
Applications
- General purpose bipolar stepper motor control
- Automation equipment requiring integrated motor driving
- Industrial control systems utilizing parallel interfaces
Procurement Notes
Verify the specific suffix '8,EL' against official Toshiba documentation to confirm tape and reel packaging specifications. Ensure compatibility with existing PCB footprints for the 28-HSOP package. Confirm RoHS compliance status matches project requirements. Check for obsolescence notices as this part may be subject to lifecycle changes.
Selection Notes
Select this component when a 3A output current is required for bipolar stepper applications. The parallel interface necessitates sufficient GPIO availability on the host microcontroller. Consider the 28-HSOP package size and thermal dissipation requirements due to the integrated power stage. Verify that the 10V to 38V load voltage range aligns with the motor specifications.
Part Context
This part belongs to the TB6221x series of motor drivers from Toshiba Semiconductor and Storage. The series includes variants such as the TB62213, TB62214, and TB62215, which differ primarily in output current ratings and package types. The TB62218 specifically offers higher current capacity compared to lower-end models in the same family.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include the TB62213AFG,C8,EL and TB62218AFTG,C8,EL. Verify pinout and electrical characteristics before substitution.
