TMC-UPS-2A24V-(A)-EVAL / TMC-UPS-10A70V-(A)-EVAL is a universal Power Stage.

It drives up to 2A / 10A of current and is tolerant to supply voltages up to 24V / 70V. It uses half bridge gate drivers and discrete MOSFETs as well as standard connectors for supply and motor connection. Current measurement is implemented by inline shunt amplifiers.

The Power Stages TMC-UPS-2A24V-A-EVAL and TMC-UPS-10A70V-A-EVAL (5V supply for shunt amplifiers) are optimized for usage with TMC4671-EVAL.

TMC4671-TOSV-REF is an open source reference design for ventilators / respirator systems. It is a BDLC servo driver for voltages from +12V to +36V and motor RMS phase currents up to 6A. It offers a wide range of connectivity with its SBC connector in Raspberry Pi style, the addon board header for a standard or custom pressure sensor addon board, and general purpose I/O. Communication is via standard TTL UART or RS485 (when using the standard addon board TOSV-SENSOR-REF).

This USB-2-RTMI offers USB interface conversion for the Real-Time Monitoring Interface of the TMC4671 FOC controller IC. The interface converter is based on the FTDI FT4222H USB High-Speed to SPI bridge. It is USB bus powered and offers basic ESD protection. USB-2-RTMI comes with connections cables for the RTMI connector and Micro USB.

Please note that USB-2-RTMI V2.0 version includes galvanic isolation between USB and RTMI connector. This device will work with the latest TMC4671-LA FOC controller IC but not with the previous version TMC4671-ES.
USB-2-RTMI V1.0 is compatible with both TMC4671-LA and TMC4671-ES.

It offers the same tiny 10pin connector with same pin assignment for the RTMI interface as it can be found on the TMC4671-LA line of evaluation boards.

The TMC6100-EVAL allows you to explore all functions of the TMC6100-LA.

The TMC6100-EVAL-KIT is a set of one MCU board Landungsbruecke, two Eselsbruecke bridge boards, one TMC4671-EVAL motion controller board as well as one TMC6100-EVAL driver board.

In addition we recommend to use the USB adapter for real-time-monitoring interface (RTMI): USB-2-RTMI.

The EVAL-KIT + USB-2-RTMI allows for a quick and simple start within only minutes to make your motor turning, while still providing full access to all registers and full functionality and diagnostics.

For diagnosis, all signals between MCU and TMC6100 are accessible with probes on the bridge board. TMC6100-EVAL can be used with or without the Landungsbruecke MCU board.

All you need to get started is a power supply and ADI Trinamic's free and easy to use TMCL-IDE. This graphical user interface allows quick setup and supports the use of commands in direct mode, monitors real-time behavior visualized in graphs, and logs and stores data. All settings can simply be exported for your own firmware project.
