TMC2202-WA

Motor Drivers, Controllers Overview

The TMC2202-WA is a fully integrated bipolar stepper motor driver IC designed for general-purpose motion control applications. It supports a supply voltage range of 4.8V to 36V and delivers an RMS current capability of 1.4A. The device features a 12 MHz operating frequency and dissipates up to 2.5W of power. It utilizes StealthChop2 technology for ultra-silent operation and SpreadCycle for high dynamic performance. The component is housed in a QFN-32 package.

Motor Drivers, Controllers Feature Summary

• Integrates StealthChop2 technology for silent motor operation at low speeds and standstill
• Supports SpreadCycle chopper mode for high dynamic torque and precise control
• Features MicroPlyer interpolation for smooth 256 microstep resolution
• Includes automatic standby current reduction to minimize power consumption

Motor Drivers, Controllers Applications

• 3D printers and additive manufacturing equipment
• Office automation and home appliance systems
• CCTV surveillance and security camera pan-tilt mechanisms
• HVAC valve actuators and fan controls

Motor Drivers, Controllers Procurement Notes

Verify the specific suffix (WA-T) against the manufacturer's official datasheet to confirm pinout compatibility and tape-and-reel packaging specifications. Ensure the ordering part number matches the required temperature grade and output current ratings documented in the Analog Devices product specification before finalizing procurement.

Motor Drivers, Controllers Selection Notes

Select this component when silent operation is critical, as it combines StealthChop2 for noise reduction with SpreadCycle for robustness. It is suitable for applications requiring up to 1.4A RMS current within a 36V supply limit. Consider the UART interface for configuration if advanced parameter tuning is needed over simple STEP/DIR control.

Motor Drivers, Controllers Part Context

The TMC2202 belongs to the Trinamic family of ultra-silent stepper motor drivers, sharing pinning compatibility with the TMC2208 and TMC2224. This series is engineered for two-phase stepper motors, offering a balance of high efficiency and low acoustic noise through advanced chopper algorithms and integrated power MOSFETs.

Motor Drivers, Controllers Replacement Considerations

The TMC2208 and TMC2224 are officially documented as pin-compatible alternatives within the same product family. Verify that the higher current or voltage capabilities of these substitutes align with the specific application requirements before substitution.
