KG Hamburg, Germany TMC5130A DATASHEET (Rev. 1.11 / 2015-OCT-08) 2 APPLICATION EXAMPLES: HIGH VOLTAGE MULTIPURPOSE USE The TMC5130A scores with complete motion controlling features, integrated power stages, and power density. It offers a versatility that covers a wide spectrum of applications from battery powered systems up to embedded applications with 2A motor current per coil. The TMC5130A contains the complete intelligence which is required to drive a motor. Receiving target positions the TMC5130A manages motor movement. Based on TRINAMICs unique features stallGuard2, coolStep, dcStep, spreadCycle, and stealthChop, the TMC5130A optimizes drive performance. It trades off velocity vs. motor torque, optimizes energy efficiency, smoothness of the drive, and noiselessness. The small form factor of the TMC5130A keeps costs down and allows for miniaturized layouts. Extensive support at the chip, board, and software levels enables rapid design cycles and fast time-to-market with competitive products. High energy efficiency and reliability deliver cost savings in related systems such as power supplies and cooling. MINIATURIZED DESIGN FOR ONE STEPPER MOTOR Ref. An ABN encoder interface with scaler Switches unit and two reference switch inputs are SPI High-Level used to control motor movement. M CPU TMC5130A Interface Encoder COMPACT DESIGN FOR UP TO 255 STEPPER MOTORS An application with 2 stepper motors is shown. Additionally, the ABN Encoder interface and two reference switches can UART High-Level CPU TMC5130A M be used for each motor. A single CPU Interface controls the whole system. The CPU- Addr. board and the controller / driver boards are highly economical and space saving. TMC5130A M Addr. Up to 255 TMC5130 can be addressed. TMC5130-EVAL EVALUATION BOARD The TMC5130-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 TMC5130 evaluation board system consists of three parts: STARTRAMPE (base board), ESELSBRCKE (connector board including several test points), and TMC5130-EVAL.
