TMC223-SI

Motor Drivers, Controllers Overview

The TMC223-SI is a microstepping stepper motor controller and driver designed for decentralized mechatronic applications. It operates with an 8V to 29V supply voltage and delivers up to 800mA output current. The device supports microstep resolutions up to 256 steps per full step and features integrated IIC serial communication. It includes user-programmable OTP memory for storing motor parameters and enables autonomous execution of time-critical tasks after initialization.

Motor Drivers, Controllers Feature Summary

• Integrated microstepping control with high resolution
• Autonomous operation of time-critical motion tasks
• User-programmable non-volatile memory for configuration
• Compact surface-mount packaging

Motor Drivers, Controllers Applications

• Decentralized mechatronic functions
• Stepper motor control systems
• Automated positioning devices

Motor Drivers, Controllers Procurement Notes

Verify the specific suffix 'SI' indicates the SOIC-20 package variant. Confirm the operating temperature range matches your environmental requirements, as this variant is rated for -40°C to +85°C. Ensure the IIC interface compatibility aligns with your system's master controller. Validate that the 800mA current rating suffices for your motor load without external heat sinking constraints.

Motor Drivers, Controllers Selection Notes

Select this component when a compact, cost-effective solution for stepper motor control is required. It is suitable for applications needing integrated microstepping and sensorless stall detection capabilities within a small footprint. Consider the 800mA limit for smaller motors where external drivers are unnecessary. The IIC interface simplifies wiring compared to parallel interfaces.

Motor Drivers, Controllers Part Context

This part belongs to the TMC223 family from Analog Devices/Maxim Integrated, which combines motion control and power driving in a single IC. Unlike higher-end models such as the TMC2240, it lacks advanced features like SpreadCycle or StallGuard but offers a simpler interface and lower cost for basic automation tasks.

Motor Drivers, Controllers Replacement Considerations

Direct substitutes include other TMC223 variants with different packages, such as TMC223-TQFN. Cross-family replacements may require significant redesign due to differences in pinout, current capacity, and feature sets.
