DESCRIPTION
The TMC5072 is a dual high performance
stepper motor controller and driver IC
with serial communication interfaces. It
combines flexible ramp generators for
automatic target positioning with
industries’ most advanced stepper motor
drivers. Based on TRINAMICs
sophisticated stealthChop chopper, the
driver ensures absolutely noiseless
operation combined with maximum
efficiency and best motor torque. High
integration, high energy efficiency and a
small form factor enable miniaturized
and scalable systems for cost effective
solutions. The complete solution reduces
learning curve to a minimum while
giving best performance in class.

Figure 1.1 Basic application and block diagram
opt. driver enable
The TMC5072 motion controller and driver chip is an intelligent power component interfacing between
the CPU and one or two stepper motors. All stepper motor logic is completely within the TMC5072. No
software is required to control the motor – just provide target positions. The TMC5072 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 TMC5072 uses stealthChop, dcStep, coolStep, and
stallGuard2 automatically to optimize every motor movement. The clear concept and the
comprehensive solution save design time.
1.1 Key Concepts
The TMC5072 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.
stealthChop™
dcStep™
stallGuard2™
coolStep™
spreadCycle™
sixPoint™
No-noise, high-precision chopper algorithm for inaudible motion and inaudible
standstill of the motor.
Load dependent speed control. The motor moves as fast as possible and never loses
a step.
High-precision load measurement using the back EMF on the motor coils.
Load-adaptive current control which reduces energy consumption by as much as
75%.
High-precision chopper algorithm available as an alternative to the traditional
constant off-time algorithm.
Fast and precise positioning using a hardware ramp generator with a set of four
acceleration / deceleration settings. Quickest response due to dedicated hardware.
