Analog Devices Inc./Maxim Integrated TMCM-0013-2A

Overview

TMCM-0013-2A from TRINAMIC Motion Control is a galvanically isolated motor phase current measurement interface board for lab use, supporting 2 A nominal RMS primary current (±19.2 A max range), 7–35 V DC or USB 5 V supply, and direct oscilloscope connection via SMA-to-BNC cables or probe clamps.

For engineers reviewing the TMCM-0013-2A datasheet, TMCM-0013-2A pinout, TMCM-0013-2A application, or TMCM-0013-2A equivalent, this tool enables accurate, low-noise, isolated current visualization of stepper, BLDC, and DC motor phases without high-cost current probes-ideal for motor control validation, thermal stress analysis, and waveform debugging in R&D labs.

Technical Context

The TMCM-0013-2A integrates LEM LTS 6-NP transducers to deliver galvanic isolation up to 2.5 kV RMS between motor power circuits and measurement outputs. It provides analog voltage output (0–5 V) linearly proportional to primary current, with 2.5 V mid-scale zero-current offset and ±0.2% accuracy at 25°C.

Designed for benchtop integration, it accepts dual power sources (USB-C or external 7–35 V), features screw terminals for motor phase connections, and offers SMB connectors plus soldering eyelets for flexible oscilloscope interfacing-no firmware, configuration, or host controller required.

FAQ

What is the primary function of the TMCM-0013-2A?

The TMCM-0013-2A is a galvanically isolated motor phase current measurement interface board that converts motor phase current into a 0–5 V analog output for oscilloscope visualization. It uses LEM LTS 6-NP transducers and requires no configuration or software-making it a standalone lab tool for stepper, BLDC, and DC motor current analysis. The TMCM-0013-2A delivers ±0.2% accuracy at 25°C and supports ±19.2 A peak measurement range.

Does the TMCM-0013-2A require external power or can it run solely from USB?

The TMCM-0013-2A supports dual power modes: it operates from either a 5 V USB-C supply or an external 7–35 V DC source via screw terminals. USB-only operation is fully functional for low-power probing scenarios, while external supply enables higher noise immunity and sustained use during extended motor tests. The TMCM-0013-2A automatically selects the active source without user intervention.

What oscilloscope interfaces does the TMCM-0013-2A support?

The TMCM-0013-2A provides two oscilloscope interface options: SMA connectors (with included SMA-to-BNC cables) and soldering eyelets for direct probe clamp attachment. Both paths deliver the same 0–5 V analog output referenced to the board's isolated ground. No signal conditioning or attenuation is needed-the TMCM-0013-2A output matches standard oscilloscope input impedance and voltage ranges.

How does the TMCM-0013-2A differ from the TMCM-0013-3A and TMCM-0013-6A variants?

The TMCM-0013-2A, TMCM-0013-3A, and TMCM-0013-6A share identical mechanical design, isolation architecture, and interface layout-but differ only in nominal RMS current rating (2 A, 3 A, or 6 A) and corresponding transducer gain scaling. All three use the same LEM LTS 6-NP sensor and deliver ±19.2 A maximum range. The TMCM-0013-2A is optimized for high-resolution measurement of low-current motors such as NEMA 8–11 steppers.

Is the TMCM-0013-2A suitable for production environments or only lab use?

The TMCM-0013-2A is explicitly designed as a lab tool-not a production-grade sensor module. Its certification, thermal derating, and long-term stability are validated for R&D, validation, and bench characterization only. For embedded current sensing in end products, TRINAMIC recommends integrated driver ICs with on-chip current sense (e.g., TMC2130, TMC2209). The TMCM-0013-2A remains a dedicated interface board & lab tool per its official documentation.
