Passive Braking and freewheeling mode Industries most advanced stepper motor driver enables miniaturized designs with Full Protection & Diagnostics low external component count for cost- 2 Small Size 5x6mm QFN36 package or TQFP48 package effective and highly competitive solutions. BLOCK DIAGRAM TRINAMIC Motion Control GmbH & Co. KG Hamburg, Germany TMC2130 DATASHEET (Rev. 1.11 / 2019-NOV-07) 2 APPLICATION EXAMPLES: HIGH VOLTAGE MULTIPURPOSE USE The TMC2130 scores with power density, integrated power MOSFETs, and a versatility that covers a wide spectrum of applications from battery systems up to embedded applications with 2.0A motor current per coil. Based on StallGuard2, CoolStep, DcStep, SpreadCycle, and StealthChop, the TMC2130 optimizes drive performance and keeps costs down. It considers velocity vs. motor load, realizes energy savings, smoothness of the drive and noiselessness. Extensive support at the chip, board, and software levels enables rapid design cycles and fast time-to-market with competitive products. MINIATURIZED DESIGN FOR ONE STEPPER MOTOR In this application, the CPU initializes the 0A+ TMC2130 motor driver via SPI interface and N High-Level S/D controls motor movement by sending step S CPU 0A- TMC2130 Interface and direction signals. A real time software 0B+ realizes motion control. 0B- SPI DESIGN FOR DEMANDING APPLICATIONS WITH S-SHAPED RAMP PROFILES The CPU initializes the TMC4361 motion 0A+ controller and the TMC2130. Thereafter, it N SPI TMC4361 SPI High-Level sends target positions to the TMC4361. Now, S TMC2130 0A- CPU Motion Interface S/D Controller the TMC4361 takes control over the TMC2130. 0B+ 0B- Combining the TMC4361 and the TMC2130 SPI offers diverse possibilities for demanding applications including servo drive features. COMPACT DESIGN FOR UP TO THREE STEPPER MOTORS Here, an application with up to three stepper 0A+ motors is shown. A single CPU combined STEP/ N TMC429 DIR SPI High-Level with a TMC429 motion controller manages S CPU Motion TMC2130 0A- Interface Controller the whole stepper motor driver system. This 0B+ 0B- design is highly economical and space SPI saving if more than one stepper motor is needed.
