Product specifications
TRINAMIC TMC261-PA
The TMC261 drivers for twophase stepper motors offer an industryleading feature set, including highresolution microstepping, sensorless mechanical load measurement, loadadaptive power optimization, and lowresonance chopper operation. Standard SPI™ and STEP/DIR interfaces simplify communication. Integrated power MOSFETs handle motor currents up to 2A per coil. Integrated protection and diagnostic features support robust and reliable operation. High integration, high energy efficiency and small form factor enable miniaturized designs with low external component count for cost-effective and highly competitive solutions.
