APPLICATION EXAMPLES: SIMPLE SOLUTIONS – HIGHLY EFFECTIVE
The TMC2225 scores with power density, integrated power MOSFETs, smooth and quiet operation, and
a congenial simplicity. The TMC2225 covers a wide spectrum of applications from battery systems to
embedded applications with up to 2A motor current per coil. TRINAMICs unique chopper modes
SpreadCycle and StealthChop2 optimize drive performance. StealthChop reduces motor noise to the
point of silence at low velocities. Standby current reduction keeps costs for power dissipation and
cooling down. Extensive support enables rapid design cycles and fast time-to-market with competitive
products.

In this example, configuration is hard
wired via pins. Software based motion
control generates STEP and DIR
(direction) signals, INDEX and ERROR
signals report back status information.

A CPU operates the driver via step and
direction signals. It accesses diagnostic
information and configures the
TMC2225 via the UART interface. The
CPU manages motion control and the
TMC2225 drives the motor and smoo-
thens and optimizes drive performance.
The TMC2225-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 TMC2225 evaluation
board system consists of three parts:
LANDUNGSBRÜCKE (base board),
ESELSBRÜCKE (connector board with
test points), and TMC2225-EVAL.
