DESCRIPTION
The TMC5062 is a high performance motion
controller and driver 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
velocity and power optimization, and low-
resonance chopper operation. Standard SPI™
interface and an optional UART based single
wire interface simplify communication.
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.
