TMC2208-LA

Motor Drivers, Controllers Overview

The TMC2208-LA is a bipolar stepper motor driver IC from the TMC2208 series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 5.5V to 36V and delivers an output current of 1.2A. The device features a 28-VFQFN package with exposed pad, measuring 5x5 mm. It supports step resolutions from full step to 1/256 microstep. The operational temperature range extends from -40°C to +125°C (TJ). Interfaces include Logic and UART for configuration.

Motor Drivers, Controllers Feature Summary

• Integrates StealthChop2 and SpreadCycle chopper modes for silent operation and high dynamic control
• Supports automatic standby current reduction to minimize power consumption during idle states
• Includes microPlyer microstep interpolation to enhance motion smoothness beyond native resolution
• Features stallGuard2 torque monitoring for load-dependent speed control

Motor Drivers, Controllers Applications

• Factory automation systems requiring precise motion control
• Home automation devices such as smart locks and blinds
• Security equipment including IP cameras and access control mechanisms
• Textile machinery applications needing quiet stepper operation

Motor Drivers, Controllers Procurement Notes

Verify the specific suffix 'LA' against official Analog Devices documentation to confirm pinout and thermal pad specifications. Ensure compatibility with the required UART baud rates and logic levels for your host controller. Check moisture sensitivity level handling procedures during assembly. Confirm RoHS compliance status for your region's regulatory requirements before finalizing component selection.

Motor Drivers, Controllers Selection Notes

Select this component when silent operation is critical due to its StealthChop technology. Consider the 1.2A output capability for driving small to medium bipolar stepper motors. Evaluate the UART interface needs for complex configuration versus simpler Step/Dir interfaces available in other variants. Assess thermal management requirements given the QFN-28 package and operating temperature range.

Motor Drivers, Controllers Part Context

The TMC2208-LA belongs to the Trinamic TMC2208 family of autonomous stepper motor drivers. It is designed for applications demanding low noise and high precision. The 'LA' suffix typically denotes a specific tape and reel or packaging variant within the broader TMC2208 product line, sharing core functional characteristics with other TMC2208 derivatives.

Motor Drivers, Controllers Replacement Considerations

TMC2209-LA offers higher current capacity and StallGuard2 support but requires different voltage considerations. TMC2208-SILENTSTEPSTICK is an evaluation board containing the TMC2208, not a direct replacement. Verify pin compatibility and firmware settings when substituting with other TMC2208 variants.
