It offers a versatility that covers a wide spectrum of applications from battery systems up to embedded applications with 1.5A motor current per coil. The small form factor 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. Switches The stepper motor driver outputs are switched in SPI High-Level parallel. A dual ABN encoder M CPU TMC5072 Interface interface and two reference switch inputs are used. Encoder COMPACT DESIGN FOR UP TO 510 STEPPER MOTORS An application for up to 510 Motor 1 stepper motors is shown. The UART single wire diffe- M UART High-Level rential interface allows for a CPU TMC5072 Interface decentralized distributed M system with a minimized number of components. Motor 2 Additionally, an ABN Motor 3 encoder and up to two reference switches can be M used for each motor. A TMC5072 single CPU can control the M whole system. The CPU- board and controller / driver Motor 4 boards are highly economi- cal and space saving. Up to 255 TMC5072 can be addressed. TMC5072-EVAL EVALUATION BOARD EVALUATION & DEVELOPMENT PLATFORM The TMC5072-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 TMC5072 evaluation board system consists of three parts: STARTRAMPE (base board), ESELSBRCKE (connector board including several test points), and Layout for Evaluation TMC5072-EVAL.
