TMC222-SI

Motor Drivers, Controllers Overview

The TMC222-SI is a system-on-chip integrating an I²C interface, positioning controller, and two-phase stepper motor driver. It supports continuous output currents up to 570mA per channel, with peak capabilities reaching 800mA. The device operates on supply voltages between 3.3V and 5V, while load voltage ranges from 8V to 29V. It functions within an operating temperature range of -40°C to 85°C (TA). The chip includes RAM and OTP memory for configuration storage.

Motor Drivers, Controllers Feature Summary

• Integrates I²C interface and positioning controller for autonomous time-critical task execution after initialization.
• Utilizes SixPoint™ ramp profile technology to ensure seamless and smooth motor movement.
• Features onboard RAM and OTP memory for persistent configuration storage without external components.

Motor Drivers, Controllers Applications

• General purpose motion control systems
• Office automation equipment
• Home automation devices

Motor Drivers, Controllers Procurement Notes

Verify the specific suffix 'SI' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the I²C address configuration matches the target system design. Confirm that the required coil current does not exceed the 570mA continuous rating without adequate thermal management solutions.

Motor Drivers, Controllers Selection Notes

Select this component when a compact solution combining control logic and power driving is required. It is suitable for applications needing microstepping resolution via software commands rather than hardware pins. Consider thermal dissipation requirements if operating near the maximum current limit in enclosed spaces.

Motor Drivers, Controllers Part Context

This part belongs to the TMC22xx family of stepper motor drivers known for quiet operation and integrated control features. Unlike standalone drivers, it reduces board space by embedding the controller logic directly alongside the power stage, simplifying the overall system architecture for low-to-medium power applications.

Motor Drivers, Controllers Replacement Considerations

Direct substitutes may include other TMC22xx variants such as TMC2208 or TMC2226, though pinouts and feature sets differ. Verify compatibility regarding I²C communication protocols and available microstepping resolutions before swapping.
