TMC2226 DATASHEET (Rev. 1.06 / 2020-MAY-18) 2
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.

0B- UART INTERFACE FOR FULL DIAGNOSTICS AND CONTROL
A CPU operates the driver via step and direction signals. It accesses diagnostic

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.
