APPLICATION EXAMPLES: SIMPLE SOLUTIONS – HIGHLY EFFECTIVE
The TMC22xx family scores with power density, integrated power MOSFETs, smooth and quiet
operation, and a congenial simplicity. The TMC2209 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
TMC2209 via the UART interface. The
CPU manages motion control and the
TMC2209 drives the motor and smoo-
thens and optimizes drive performance.
The TMC2209-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 TMC2209 evaluation
board system consists of three parts:
STARTRAMPE (base board),
ESELSBRÜCKE (connector board with
several test points and stand-alone
settings), and TMC2209-EVAL.
