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 TMC22xx 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.

TMC2208-EVAL EVALUATION BOARD
The TMC22xx-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 TMC22xx evaluation
board system consists of three parts:
STARTRAMPE (base board), TMC2208-
BRIDGE (connector board with several
test points and stand-alone settings),
and TMC22xx-EVAL.
