Product details
Overview
TMC5160-TA from TRINAMIC Motion Control GmbH & Co. KG is a high-power stepper motor controller and driver IC with integrated motion control logic, external MOSFET gate drivers, and dual chopper modes (StealthChop2™ and SpreadCycle™). It supports 8–60 V DC supply, up to several 10 A coil current via external transistors, 256 microsteps per full step, and operates in three configurable modes: full motion controller, STEP/DIR driver with MicroPlyer™ interpolation, or standalone hardware-configured driver. It is used in high-speed 3D printers and lab automation systems requiring silent, high-torque, sensorless closed-loop positioning.
For engineers reviewing the TMC5160-TA datasheet, TMC5160-TA pinout, TMC5160-TA application, or TMC5160-TA equivalent, key selection considerations include its eTQFP-48 package with exposed thermal pad, SPI + single-wire UART interface support, StallGuard2™ for sensorless load detection, CoolStep™ for up to 75% energy reduction, and compatibility with external ABN encoders and reference switches.
Technical Context
The TMC5160-TA integrates a 32-bit SixPoint™ ramp generator with real-time velocity profiling, automatic stall response, and homing via StallGuard2™ or dual reference switches. Its dual-chopper architecture enables seamless mode switching between StealthChop2™ (for ultra-quiet standstill and low-speed operation) and SpreadCycle™ (for high-dynamic, low-resonance mid-to-high speed motion), both programmable via SPI or hardware pins.
It features an ABN encoder interface with 32-bit counter and programmable scaler, two dedicated reference switch inputs (REFL/STEP and REFR/DIR), and diagnostic outputs (DIAG0/SWN and DIAG1/SWP) supporting interrupt-driven error handling. The device uses external sense resistors and MOSFETs, with internal charge pump (VCP) and dual voltage regulators (5VOUT, 12VOUT) for gate drive and I/O supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar stepper motor controller/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMC5130-TA | Integrated MOSFETs rated for ≤1.4 A coil current; same SPI/UART interface and firmware compatibility but no external gate drivers. | Targeted at compact, low-power systems (e.g., portable instruments) where board space and heat dissipation constrain external FET use. | Select TMC5130-TA when motor current ≤1.4 A and PCB area is critical; TMC5160-TA remains required for >2 A or industrial-grade thermal resilience. |
| TMC5072-LA | Dual-channel 2A-per-coil driver with integrated MOSFETs; supports two independent stepper motors on one die; lacks StallGuard2™ and DcStep™. | Optimized for multi-axis OEM equipment (e.g., desktop CNC, dual-extruder printers) needing coordinated motion but not sensorless load control. | Choose TMC5072-LA for cost-sensitive dual-motor designs without need for stall detection; TMC5160-TA is preferred for single-axis high-torque, high-intelligence applications. |
Compared with TMC5130-TA and TMC5072-LA, the TMC5160-TA uniquely combines external high-current drive capability (several 10 A), sensorless load intelligence (StallGuard2™/CoolStep™/DcStep™), and dual-chopper flexibility-making it the only option for scalable, high-reliability stepper systems demanding both power and precision.

FAQ
What is the maximum motor current supported by the TMC5160-TA?
The TMC5160-TA itself does not source motor current-it drives external N-channel MOSFETs. With appropriate external FETs and sense resistors, it supports coil currents from 1 A up to several 10 A. The actual limit depends on MOSFET selection, PCB layout, and thermal management. The TMC5160-TA's gate drivers and current regulation circuitry are validated for this full range, and its datasheet specifies design guidelines for ≥10 A operation.
Does the TMC5160-TA require an external clock source?
No, the TMC5160-TA includes an internal oscillator and can operate without an external clock. However, it also supports optional 12–16 MHz external crystal or clock input via the CLK_IN pin for improved timing accuracy in synchronized multi-axis systems. The internal oscillator is sufficient for most standalone and STEP/DIR applications, while the external option is recommended for time-critical motion coordination across multiple TMC5160-TA devices.
Can the TMC5160-TA operate without a microcontroller?
Yes, the TMC5160-TA supports true standalone operation using hardware configuration pins (SD_MODE, SPI_MODE, CFG0–CFG6). In this mode, it accepts STEP/DIR signals directly, applies MicroPlyer™ interpolation, and executes CoolStep™ and StealthChop2™ autonomously-no SPI or UART communication required. Configuration such as microstep resolution, run/hold current, and chopper mode is set via pull-up/pull-down resistors on CFG pins, enabling fully autonomous motion control.
How does StallGuard2™ function without an encoder on the TMC5160-TA?
StallGuard2™ on the TMC5160-TA is a sensorless technique that measures back-EMF-induced voltage fluctuations in the motor windings during each chopper cycle. It correlates these measurements with motor load and position to detect mechanical resistance-enabling stall detection, homing, and CoolStep™ current adaptation without encoder hardware. This method is validated across motor types and loads, and its 10-bit resolution allows precise threshold tuning via the SGTHRS register in the TMC5160-TA's register map.
What thermal management is required for the TMC5160-TA in high-current applications?
The TMC5160-TA uses an eTQFP-48 package with an exposed thermal pad (GNDD/GNDP) that must be soldered to a large copper pour connected to internal/external ground planes. For >5 A coil current, a minimum 400 mm² thermal pad with ≥4 thermal vias (0.3 mm diameter, spaced ≤1 mm apart) is recommended. The datasheet specifies θJA = 35 °C/W with proper layout; exceeding 110 °C junction temperature triggers thermal shutdown. Forced air cooling is advised above 8 A continuous operation.
