DESCRIPTION
The TMC5031 is a low cost motion controller
and driver IC for up to two stepper motors.
It combines two flexible ramp motion
controllers with energy efficient stepper
motor drivers. The drivers support two-phase
stepper motors and offer an industry-leading
feature set, including high-resolution
microstepping, sensorless mechanical load
measurement, load-adaptive power optimi-
zation, and low-resonance chopper operation.
All features are controlled by a standard
SPI™ interface. 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.
