DESCRIPTION
The TMC2660 driver for two-phase stepper
motors offers an industry-leading feature
set,
including
high-resolution
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 2.2A RMS continuously or
2.8A RMS boost current 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.
