DESCRIPTION
The TMC5160 / TMC5161A is a compact
stepper motor controller and driver IC.
Its power stage is optimized for lowest
power dissipation and highest dynamics
with Nema 17 and Nema 23 motors. It
combines a flexible ramp generator for
automatic target positioning with in-
dustries’ most advanced stepper motor
driver. Based on TRINAMICs sophisticated
SpreadCycle and StealthChop choppers, it
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. Interface-compatible to TMC5160.

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.

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.
