DESCRIPTION
The TMC2226 is an ultra-silent motor driver
IC for two phase stepper motors. TRINAMICs
sophisticated StealthChop2 chopper ensures
noiseless operation, maximum efficiency
and best motor torque. Its fast current
regulation and optional combination with
SpreadCycle allow highly dynamic motion
while adding. StallGuard for sensorless
homing. The integrated power MOSFETs
handle motor currents up to 2A RMS with
protection and diagnostic features for robust
and reliable operation. A simple to use UART
interface opens up tuning and control
options. Store application tuning to OTP
memory. Industries’ most advanced
STEP/DIR stepper motor driver family
upgrades designs to noiseless and most
precise operation for cost-effective and
highly competitive solutions.

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 TMC2226 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.

A CPU operates the driver via step and
direction signals. It accesses diagnostic
information and configures the
TMC2226 via the UART interface. The CPU
manages motion control and the
TMC2226 drives the motor and smoo-
thens and optimizes drive performance.
The TMC2226-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 TMC2226 evaluation board system
consists of three parts: STARTRAMPE
(base board), ESELSBRÜCKE (connector
board with several test points and
stand-alone settings), and TMC2226-
EVAL.
