TMC5161A DATASHEET (Rev. 1.05 / 2019-NOV-18)
APPLICATION EXAMPLES: COMPACT DRIVES – MULTIPURPOSE USE
The TMC5161 scores with complete motion controlling features, a powerful integrated MOSFET driver stage,
and high-quality current regulation. It offers a versatility that covers a wide spectrum of applications from
battery powered, high efficiency systems up to embedded applications with 4A motor current per coil. The
TMC5161 contains the complete intelligence which is required to drive a motor. Receiving target positions
the TMC5161 manages motor movement. Based on TRINAMICs unique features StallGuard2, CoolStep,
DcStep, SpreadCycle, and StealthChop, the TMC5161 optimizes drive performance. It trades off velocity vs.
motor torque, optimizes energy efficiency, smoothness of the drive, and noiselessness. The small form
factor of the TMC5161 keeps costs down and allows for miniaturized layouts. Extensive support at the chip,
board, and software levels enables rapid design cycles and fast time-to-market with competitive products.
High energy efficiency and reliability deliver cost savings in related systems such as power supplies and
cooling. For smaller designs, the compatible, integrated TMC5130 driver provides 1.4A of motor current.
MINIATURIZED DESIGN FOR ONE STEPPER MOTOR
CPU SPI TMC5161
An ABN encoder interface with scaler unit
and two reference switch inputs are used to
ensure correct motor movement. Automatic
interrupt upon deviation is available.
COMPACT DESIGN FOR MULTIPLE STEPPER MOTORS
An application with 2 stepper motors is
shown. Additionally, the ABN Encoder
interface and two reference switches can be
used for each motor. A single CPU controls
the whole system, as there are no real time
tasks required to move a motor. The CPU-
board and the controller / driver boards are
highly economical and space saving.

The TMC5161-EVAL is part of TRINAMICs
universal evaluation board system which
provides a convenient handling of the
hardware as well as a user-friendly
software tool for evaluation. The
TMC5161 evaluation board system
consists of three parts:
LANDUNGSBRÜCKE (base board),
ESELSBRÜCKE (connector board including
several test points), and TMC5161-EVAL.
stepper controller/driver up to 3.5A RMS; QFN10x10 10 x 10
-T denotes tape on reel packed devices

Hint: TMC5161 in this manual always refers to both, the TMC5161A and TMC5161, unless explicitly noted
with “non-A-version” or “A-version”. The A-version compatibly replaces the non-A-version.
