Product details
Overview
TMC2160-TA from TRINAMIC Motion Control GmbH & Co. KG is a high-voltage, external-MOSFET stepper motor driver IC for 2-phase bipolar stepper motors, supporting 8–60 V DC supply, up to 256 microsteps per full step, and featuring StealthChop2™ for silent operation and StallGuard2™ for sensorless load detection - deployed in high-speed 3D printers and lab automation motion stages.
For engineers reviewing the TMC2160-TA datasheet, TMC2160-TA pinout, TMC2160-TA application, or TMC2160-TA equivalent, key selection criteria include SPI/Step-Dir dual interface support, integrated SpreadCycle™/StealthChop2™ chopper selection, CoolStep™ current adaptation, DcStep™ load-dependent speed control, and TQFP-EP 48-pin thermal performance with exposed die pad.
Technical Context
The TMC2160-TA implements two independent chopper modes - StealthChop2™ (voltage-mode, auto-tuned, ultra-quiet at standstill and low speed) and SpreadCycle™ (current-mode, cycle-by-cycle, high-dynamic torque delivery) - selectable via SPI or hardware pin. It uses external N-channel MOSFETs per half-bridge, with dedicated gate drivers (HA1/HA2/HB1/HB2), bootstrap capacitor interfaces (CA1/CA2/CB1/CB2), and charge pump (CPI/CPO/VCP) for high-side drive.
Current regulation relies on four Kelvin-connected sense resistor terminals (SRAH/SRAL/SRBH/SRBL) enabling precise phase-A/B RMS current measurement. Diagnostics include open-load detection, overtemperature shutdown, short-circuit protection, and dual DIAG outputs (DIAG0/DIAG1) configurable as interrupt or status flags - all managed through 40-bit SPI command/status register protocol.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8–60 V DC motor supply (VS); supports industrial and battery-powered high-voltage systems without external DC-DC conversion. |
| Microstep Resolution | Up to 256 microsteps/full step via MicroPlyer™ interpolation - enables smooth motion from coarse STEP/DIR inputs without external microstepping controller. |
| Chopper Modes | StealthChop2™ (auto-tuned voltage chopper) + SpreadCycle™ (adaptive current chopper) - selectable per motion profile for noise vs. dynamics trade-off. |
| Stall Detection | StallGuard2™ provides real-time mechanical load feedback using coil back-EMF analysis - enables sensorless homing and closed-loop-like positioning without encoder. |
| Energy Optimization | CoolStep™ reduces motor current by up to 75% under light load - lowers PCB temperature rise, eliminates need for heatsinks in compact designs. |
| Interface Options | SPI (40-bit command/status) + Step/Dir (with dedge mode for rising/falling edge counting) - supports both embedded CPU control and standalone motion systems. |
| Protection Features | Overtemperature shutdown, open-load diagnostics, short-circuit detection, undervoltage lockout - ensures robust operation in unattended industrial environments. |
Pinout & Package
TMC2160-TA is housed in a thermally enhanced TQFP-EP 48-pin package (7×7 mm² body, 9×9 mm² with leads), with exposed die pad soldered to PCB ground plane for efficient heat dissipation - critical for sustained high-current motor drive operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HA1, HA2, HB1, HB2 | High-side gate drivers | Drive external N-MOSFET gates in H-bridge configuration; require bootstrap capacitors (CA1/CA2/CB1/CB2) for level-shifting. |
| LA1, LA2, LB1, LB2 | Low-side gate drivers | Directly drive low-side N-MOSFETs; powered from 12VOUT regulator - decoupled with ≥2.2 µF ceramic capacitor. |
| SRAH, SRAL, SRBH, SRBL | Kelvin sense resistor connections | Enable accurate phase current sensing by separating high-side and GND-side sense paths - essential for StallGuard2 and CoolStep accuracy. |
| STEP, DIR, SPI_MODE | Digital control inputs | STEP/DIR enable standalone motion; SPI_MODE selects between SPI interface (high) or hardware CFG pin mode (low). |
| DIAG0, DIAG1 | Diagnostics outputs | Open-drain status flags for stall, overtemperature, short-circuit, or error conditions - configurable via SPI registers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stepper motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMC2160A-TA | Pin-compatible A-version with minor internal enhancements; fully backward compatible with TMC2160-TA firmware and layout. | Identical use cases; preferred for new designs due to extended production lifecycle and updated ESD robustness. | Select TMC2160A-TA when sourcing new production builds - same footprint, no redesign needed. |
| TMC5160-TA | Integrates full motion controller (ramp generator, trajectory planning) alongside identical driver stage - requires no external CPU for basic motion. | Replaces microcontroller-based Step/Dir generation; suited for standalone motion systems where host CPU resources are constrained. | Choose TMC5160-TA only if motion profiling (S-curve ramps, multi-axis sync) is required - adds complexity but removes host dependency. |
Compared with TMC2160-TA, the TMC2160A-TA offers identical functionality with improved long-term availability, while the TMC5160-TA trades host CPU offload for increased silicon integration - making it optimal for motion-controller-constrained embedded systems but unnecessary for existing Step/Dir architectures.

FAQ
What is the maximum motor supply voltage supported by the TMC2160-TA?
The TMC2160-TA supports a motor supply voltage range of 8 V to 60 V DC on the VS pin. This wide input range enables direct integration into industrial 24 V and 48 V systems, as well as battery-powered portable equipment. Operation above 60 V risks permanent damage, and minimum 8 V is required to sustain gate drive and internal regulation - verified in Absolute Maximum Ratings (Section 23) and Electrical Characteristics (Section 24.1) of the TMC2160 DATASHEET Rev. 1.10.
Does the TMC2160-TA integrate MOSFETs or require external power transistors?
The TMC2160-TA does not integrate power MOSFETs - it is a gate driver IC requiring external N-channel MOSFETs for both high-side and low-side switching in each H-bridge leg. The device provides eight dedicated gate driver outputs (HA1/HA2/HB1/HB2/LA1/LA2/LB1/LB2), bootstrap capacitor interfaces, and charge pump circuitry to support high-side drive. This architecture allows scalable current handling from 1 A to >20 A per coil, as confirmed in the "Universal high voltage driver" description and Figure 1.1 of the TMC2160 DATASHEET.
How does StealthChop2™ differ from standard chopper modes in the TMC2160-TA?
StealthChop2™ is an auto-tuned voltage-mode chopper that eliminates audible motor noise at standstill and low speeds - unlike classic constant-off-time choppers. It learns optimal timing during initial motion and dynamically adapts to velocity changes, enabling silent operation without manual tuning. In contrast, SpreadCycle™ is a current-mode chopper optimized for high-dynamic torque delivery. Both coexist in the TMC2160-TA and can be used simultaneously - StealthChop2™ at low speed, SpreadCycle™ at high speed - as detailed in Sections 1.6 and 6 of the TMC2160 DATASHEET.
Can the TMC2160-TA operate without an external microcontroller?
Yes, the TMC2160-TA supports standalone operation via hardware pin configuration (SPI_MODE = low), where STEP/DIR signals directly control motion and microstep resolution, run/hold currents, and chopper mode are set using CFG pins (CFG0–CFG6). In this mode, MicroPlyer™ interpolation and automatic standstill current reduction remain active - enabling fully autonomous motion without SPI communication. This capability is explicitly defined in Section 1.2 and Figure 1.2 of the TMC2160 DATASHEET Rev. 1.10.
What thermal management provisions does the TMC2160-TA package include?
The TMC2160-TA uses a TQFP-EP 48-pin package with an exposed die pad electrically and thermally connected to GNDD/GNDA - requiring soldering to a large PCB ground plane with multiple thermal vias. This design dissipates heat from the driver logic and gate drivers during sustained high-current operation. Layout guidelines in Section 25.1 mandate low-inductance GND routing and decoupling capacitors (e.g., 2.2 µF on 12VOUT, 100 nF on VCC) to maintain thermal stability - all validated in thermal characterization data (Section 24.3) of the official datasheet.
