Product details
Overview
TMC5160-WA from TRINAMIC Motion Control GmbH & Co. KG is a high-voltage, high-current stepper motor controller and driver IC with integrated motion control logic, 8–60 V DC operation, 256 microstep resolution, StealthChop2™ for silent standstill, and StallGuard2™ for sensorless load detection. It drives external MOSFETs to support coil currents from 1 A to several 10 A and is used in high-speed 3D printers, lab automation, and medical fluid handling systems.
For engineers reviewing the TMC5160-WA datasheet, TMC5160-WA pinout, TMC5160-WA application, or TMC5160-WA equivalent, this page delivers verified technical context, package-specific pin mapping (QFN56 Wettable Flanks), real-world design meaning of key features like CoolStep™ energy savings and DcStep™ load-dependent speed control, and validated alternative options for motion control system design.
Technical Context
The TMC5160-WA implements a fully autonomous 32-bit motion controller with SixPoint™ ramp generation, supporting target-position-based movement without host CPU intervention in Mode 1. It integrates dual chopper modes-StealthChop2™ for ultra-quiet low-velocity operation and SpreadCycle™ for high-dynamic, low-resonance current regulation-both programmable via SPI or UART.
It supports three operational modes: full motion controller (SD_MODE = low), Step/Dir with MicroPlyer™ interpolation (SD_MODE = high), and hardware-configured standalone mode (SPI_MODE = low). The QFN56 Wettable Flanks package enables automated optical inspection and robust thermal performance via exposed die pad connected to GNDD/GNDP.
Key Specifications

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 |
|---|---|---|---|
| TMC5161-TA | Same architecture but integrated MOSFETs rated for ≤ 3.5 A coil current; no external gate drivers or charge pump required. | Suitable for compact, lower-power designs where board space and external component count outweigh peak current needs. | Select TMC5161-TA when coil current ≤ 3.5 A and layout simplicity is prioritized over scalability. |
| TMC5130A-TA | Lower voltage range (4.75–46 V), smaller eTQFP32 package, reduced feature set (no encoder interface, no DcStep™). | Targeted at cost-sensitive, space-constrained embedded systems such as office automation and small CNC routers. | Choose TMC5130A-TA for sub-46 V, ≤ 1.4 A applications where StealthChop2™ and StallGuard2™ remain essential but encoder/DcStep™ are unnecessary. |
Compared with TMC5160-WA, the TMC5161-TA trades external MOSFET flexibility for integration and reduced BOM count, while the TMC5130A-TA sacrifices voltage headroom, current scalability, and advanced closed-loop features to achieve smaller footprint and lower cost - making each suitable for distinct tiers of motion system complexity.

FAQ
What is the primary function of the TMC5160-WA in a motion control system?
The TMC5160-WA serves as an integrated stepper motor controller and driver IC that autonomously manages motor movement using its built-in SixPoint™ ramp generator and dual chopper modes. Unlike basic drivers, it executes target-position commands directly - eliminating the need for host CPU motion profiling. In the TMC5160-WA, this intelligence operates alongside external MOSFETs to deliver up to several 10 A per coil, making it ideal for high-torque industrial motion systems where precision, silence, and reliability are critical.
How does the QFN56 Wettable Flanks package of the TMC5160-WA improve manufacturing yield?
The QFN56 Wettable Flanks package of the TMC5160-WA features solderable side terminals that enable automated optical inspection (AOI) of solder joints - a capability not possible with standard QFN packages. This significantly improves process control during reflow assembly, especially in high-reliability applications like medical devices. The exposed die pad also enhances thermal conduction to the PCB ground plane, supporting stable operation under continuous high-current conditions in the TMC5160-WA.
Can the TMC5160-WA operate without a microcontroller?
Yes, the TMC5160-WA supports true standalone operation via hardware pin configuration (SPI_MODE = low, SD_MODE = high), where STEP/DIR signals directly control motor motion with MicroPlyer™ interpolation and automatic standstill current reduction. In this mode, all chopper settings, microstep resolution, and CoolStep™ thresholds are set by external resistors or pull-up/pull-down configurations - allowing the TMC5160-WA to function as a self-contained motion subsystem without firmware or serial communication.
What distinguishes StealthChop2™ from SpreadCycle™ in the TMC5160-WA?
StealthChop2™ is a self-tuning voltage-mode chopper optimized for silent operation at low speeds and standstill, requiring no configuration and adapting automatically after initial motion. SpreadCycle™ is a precision current-mode chopper delivering high dynamic torque and resonance suppression across wide speed ranges. In the TMC5160-WA, both can be used independently or combined - StealthChop2™ for quiet positioning, SpreadCycle™ for high-acceleration moves - giving designers granular control over acoustic, thermal, and mechanical performance.
Does the TMC5160-WA support encoder-based closed-loop operation?
Yes, the TMC5160-WA includes a dedicated ABN incremental encoder interface with 32-bit counter, programmable prescaler, and index pulse (ENCN_DCO) input. It supports encoder-based position verification, step-loss correction, and sensorless homing - all without host CPU involvement. When used with the TMC5160-WA's StallGuard2™ and DcStep™ features, the encoder enables hybrid open/closed-loop operation that maintains positional accuracy under variable mechanical loads while preserving the simplicity of stepper motor deployment.
