ADITMC2130-LA
Overview
The TMC2130-LA is a high-performance stepper motor driver IC with integrated power MOSFETs, capable of driving up to 1.2A of current at voltages between 5.5V and 46V. It features the proprietary StealthChop technology for silent motor operation and SpreadCycle for high-speed dynamics, making it a standard choice for precision motion control. The device supports control via a classic Step/Direction interface or through a full SPI configuration for advanced diagnostics and parameter tuning.
Why Choose This Part
This driver excels by offering StealthChop for near-silent operation and StallGuard2 for sensorless homing, reducing BOM cost by eliminating physical limit switches. It integrates high-resolution microstepping (up to 1/256) through its MicroPlyer interpolation, ensuring high precision even with low-resolution input signals. Additionally, its wide supply range of 5.5V to 46V provides significant headroom for various industrial and consumer power rails.
Applications
Key Specifications
Getting Started
To evaluate the TMC2130-LA, engineers often start with the TMC2130-EVAL-KIT or the TMC2130-BOB breakout board for quick prototyping. Configuration is typically performed over SPI using Trinamic's TMCL-IDE software to tune chopper frequencies and current limits. For firmware development, ensure the thermal pad is properly soldered to a large ground plane, as the QFN36 package relies on the PCB for heat dissipation at currents near 1.2A.
