Introduction

The TMC260 and TMC261 drivers for twophase stepper motors offer an industryleading feature set, including highresolution microstepping, sensorless mechanical load measurement, load-adaptive power optimization, and low-resonance 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. The new -C types TMC260C & TMC261C improve motor silence and add low side short protection and a stand-alone mode.
