Product details
Overview
TMC2160-TA-T from TRINAMIC Motion Control GmbH & Co. KG is a high-voltage, SPI- and Step/Dir–enabled 2-phase bipolar stepper motor driver IC with integrated gate drivers for external MOSFETs. It delivers up to 1.4 A RMS coil current, operates from 8–60 V DC, supports up to 256 microsteps per full step, and implements StealthChop2™ for silent standstill and SpreadCycle™ for high-dynamic motion-used in high-speed 3D printers and lab automation systems.
For engineers reviewing the TMC2160-TA-T datasheet, TMC2160-TA-T pinout, TMC2160-TA-T application, or TMC2160-TA-T equivalent, key selection criteria include its TQFP48 package with exposed thermal pad, dual chopper mode selection (StealthChop2 vs. SpreadCycle), StallGuard2™ sensorless load detection, CoolStep™ current adaptation, and DcStep™ load-dependent speed control-all validated for industrial motion control where noise, efficiency, and stall resilience are critical.
Technical Context
The TMC2160-TA-T functions as an intelligent gate driver interface between a motion controller (e.g., TMC4361) or host CPU and external H-bridge MOSFETs. Its dual chopper architecture enables runtime switching between StealthChop2 (voltage-mode, zero audible noise at low velocity) and SpreadCycle (current-mode, optimized zero-crossing and resonance suppression).
It integrates dedicated analog sense paths (SRAL/SRAH/SRBL/SRBH) with Kelvin connections for accurate phase current measurement, supports both SPI-configured operation and hardware-pin–configured standalone mode via SPI_MODE, and embeds real-time diagnostics including open-load detection, overtemperature shutdown, and short-circuit protection on all power stages.
Key Specifications

Pinout & Package
Package: TQFP48 (7×7 mm² body, 9×9 mm² with leads), thermally enhanced with exposed GND pad requiring ≥6 vias to inner GND plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HB1, HA1, HB2, HA2 | High-side gate driver outputs | Drive external N-channel MOSFET gates in half-bridge configuration; require bootstrap capacitors (CB1, CA1, etc.) for high-side floating bias. |
| LB1, LA1, LB2, LA2 | Low-side gate driver outputs | Directly drive low-side N-MOSFET gates; referenced to 12VOUT (internal 11.5 V regulator) for robust gate turn-on. |
| SRAH, SRAL, SRBH, SRBL | Differential current sense inputs | Kelvin-connected to sense resistors for accurate phase A/B current measurement-critical for StallGuard2, CoolStep, and closed-loop torque control. |
| STEP, DIR, DRV_ENN | Digital motion control inputs | Accept 3.3 V/5 V logic; support edge-triggered stepping (rising/falling), direction polarity, and hardware enable/disable of all power stages. |
| DIAG0, DIAG1 | Open-drain diagnostic outputs | Assert active-low faults (e.g., OT, short, open load); require external 47 kΩ pull-up; support interrupt-driven system monitoring. |
| CSN, SCK, SDI, SDO | SPI interface pins | 40-bit full-duplex SPI with automatic command/status framing-enables real-time register read/write for dynamic tuning and diagnostics. |
Key Features
| Feature | Design Value |
|---|---|
| StealthChop2™ | Eliminates audible motor noise at standstill and low speeds without parameter tuning-reduces mechanical resonance and improves positional stability in office automation and medical devices. |
| StallGuard2™ | Provides real-time, sensorless load measurement using back-EMF analysis-enables stall detection, sensorless homing, and feed-forward torque compensation without external encoders. |
| CoolStep™ | Reduces motor current up to 75% during light loads by adapting IRUN based on StallGuard2 feedback-lowers power dissipation, extends motor life, and eliminates need for heatsinks in compact designs. |
| DcStep™ | Maintains step accuracy under increasing mechanical load by automatically reducing velocity before stall-ensures reliable motion in pumps, valves, and liquid handling without position loss. |
| MicroPlyer™ | Interpolates coarse STEP inputs (e.g., full-step) into smooth 256-microstep motion-improves resolution and reduces vibration in high-precision CNC and 3D printing axes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stepper motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMC2130-TA-T | Lower voltage range (4.75–46 V), integrated MOSFETs (1.4 A), no external gate drivers; same SPI/Step-Dir feature set and register map. | Better suited for space-constrained, lower-power designs (e.g., desktop CNC, portable instruments) where board area and BOM count must be minimized. | Select TMC2130-TA-T when motor current ≤1.4 A and supply voltage <46 V; choose TMC2160-TA-T when driving higher-voltage motors or requiring external MOSFET flexibility. |
| TMC5160-TA-T | Includes integrated motion controller (ramp generator, position tracking); identical gate driver stage and pinout; requires no external MCU for basic motion profiles. | Ideal for standalone motion systems (e.g., ATM cash recyclers, valve actuators) needing S-curve ramps, target positioning, and auto-tuning without host processor overhead. | Choose TMC5160-TA-T when motion sequencing is handled onboard; retain TMC2160-TA-T when motion control resides in host CPU or external motion controller (e.g., TMC4361). |
Compared with TMC2130-TA-T, the TMC2160-TA-T trades integrated power stages for higher voltage capability and external MOSFET scalability; compared with TMC5160-TA-T, it removes the motion controller to reduce cost and latency in systems with centralized trajectory planning-making it optimal for high-voltage, high-flexibility stepper control where intelligence resides upstream.

FAQ
What is the maximum motor supply voltage supported by the TMC2160-TA-T?
The TMC2160-TA-T supports a motor supply voltage (VS) range of 8 V to 60 V DC. This wide input range allows direct integration into industrial 24 V and 48 V systems, as well as battery-powered equipment. Operation above 60 V risks permanent damage; always verify voltage transients and ensure adequate input filtering per Section 25 of the official datasheet. The TMC2160-TA-T maintains full functionality-including StealthChop2™, SpreadCycle™, and StallGuard2™-across this entire range.
Does the TMC2160-TA-T integrate power MOSFETs, or does it require external ones?
The TMC2160-TA-T does not integrate power MOSFETs-it is a gate driver IC designed to control external N-channel MOSFETs in a two-phase H-bridge configuration. It provides eight gate driver outputs (HA1/HA2/HB1/HB2/LA1/LA2/LB1/LB2), bootstrap capacitor interfaces, and dedicated sense inputs for precise current regulation. This architecture enables scalable current handling (beyond 1.4 A) and thermal separation, distinguishing it from fully integrated drivers like the TMC2130-TA-T.
How does StallGuard2™ function in the TMC2160-TA-T, and what design considerations apply?
StallGuard2™ in the TMC2160-TA-T performs sensorless load detection by analyzing back-EMF asymmetry during motor coil commutation. It outputs a 10-bit value proportional to mechanical load, used by CoolStep™ and DcStep™. Accurate operation requires proper PCB layout: Kelvin sense routing for SRAL/SRAH/SRBL/SRBH, minimized loop area, and avoidance of noisy digital traces near analog inputs. The TMC2160-TA-T's StallGuard2™ is calibrated per motor and must be tuned via SGTHRS register for each application.
Can the TMC2160-TA-T operate without an external microcontroller?
Yes-the TMC2160-TA-T supports standalone operation when SPI_MODE is tied low. In this mode, configuration is set via hardware pins (CFG0–CFG6), and motion is controlled solely by STEP/DIR signals. MicroPlyer™ interpolation, automatic standstill current reduction (IHOLD), and basic diagnostics remain active. However, advanced features like real-time StallGuard2™ readback, dynamic chopper switching, or register-based tuning require SPI communication with a host controller.
What thermal management practices are recommended for the TMC2160-TA-T in continuous operation?
For continuous operation, the TMC2160-TA-T requires connection of its exposed die pad to a solid internal GND plane using ≥6 thermal vias (0.3 mm diameter, spaced ≤1 mm apart). A minimum 250 mm² copper area on the top and inner layers is recommended. Avoid placing thermal relief on the pad. Ambient temperature must stay below 85°C; junction temperature must not exceed 150°C. Derating applies above 70°C ambient-consult Section 24.3 (Thermal Characteristics) in the TMC2160-TA-T datasheet for exact θJA values and power dissipation limits.
