up to 2A motor current
up to 60V DC (TMC261) or 40V DC (TMC260) *)
up to 256 microsteps per full step
10x10mm QFP-44 package
The TMC260*) and TMC261*) drivers for
two-phase stepper motors offer an
industry-leading feature set, including high-
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.
*) TMC26x refers to TMC26x and TMC26xA unless
otherwise noted. The TMC26xA is 100% compatible.
