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.

Figure 1.1 Basic application and block diagram
The TMC5062 motion controller and driver chip is an intelligent power component interfacing between
the CPU and up to two stepper motors. The TMC5062 offers a number of unique enhancements which
are enabled by the system-on-chip integration of driver and controller. The sixPoint ramp generator of
the TMC5062 uses dcStep, coolStep, and stallGuard2 automatically to optimize every motor movement:
TRINAMICs special features contribute toward lower system cost, greater precision, greater energy
efficiency, smoother motion, and cooler operation in stepper motor applications. The clear concept
and the comprehensive solution save design-in time.
1.1 Key Concepts
The TMC5062 implements several advanced features which are exclusive to TRINAMIC products. These
features contribute toward greater precision, greater energy efficiency, higher reliability, smoother
motion, and cooler operation in many stepper motor applications.
dcStep™
Load dependent speed control. The motor moves as fast as possible and never loses
a step.
stallGuard2™ High-precision load measurement using the back EMF on the motor coils.
coolStep™
Load-adaptive current control which reduces energy consumption by as much as
75%.
spreadCycle™ High-precision chopper algorithm available as an alternative to the traditional
constant off-time algorithm.
In addition to these performance enhancements, TRINAMIC motor drivers also offer safeguards to
detect and protect against shorted outputs, output open-circuit, overtemperature, and undervoltage
conditions for enhancing safety and recovery from equipment malfunctions.
