Product details
Overview
TMC2210AUU+T from Analog Devices is a standalone, pin-configurable 2-phase stepper motor driver IC with integrated H-bridges, StealthChop2 silent operation, and lossless current sensing. It delivers up to 3.0A full-scale per bridge (2.1ARMS), operates from 4.5V–36V, and supports 256 microsteps - enabling precise, quiet motion control in compact industrial motion systems.
For engineers reviewing the TMC2210AUU+T datasheet, TMC2210AUU+T pinout, TMC2210AUU+T application, or TMC2210AUU+T equivalent, key selection criteria include its thermally optimized TQFN32 package, configurable step/direction interface with MicroPlyer interpolation, integrated diagnostics (ERROR/INDEX/OV), and dual chopper modes (StealthChop2/SpreadCycle) for noise-sensitive or high-dynamic applications.
Technical Context
The TMC2210AUU+T integrates two fully independent 36V H-bridges with total RON of 0.23Ω (HS+LS), driven by a 12.5MHz internal oscillator and configurable via eight CFG pins. Its current regulation uses an external IREF resistor (12kΩ–60kΩ) to set full-scale current (1A–3A), with real-time RMS current limited to 2.1ARMS at 25°C on a four-layer PCB.
It implements dual chopper architectures: StealthChop2 for ultralow acoustic noise and zero torque ripple at standstill and low speeds, and SpreadCycle for high-torque, high-dynamic response during acceleration/deceleration. Diagnostic outputs (ERROR, INDEX, OV) provide real-time fault reporting and position reference pulses synchronized to coil B zero-crossing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5V–36V DC - supports wide-input industrial power rails without external regulators. |
| Max Full-Scale Current (per H-Bridge) | 3.0A - set via external IREF resistor; defines peak current limit of embedded regulation circuit. |
| RMS Current Rating (per H-Bridge) | 2.1ARMS at 25°C on four-layer PCB - thermal limit governs actual usable current in end application. |
| Total H-Bridge RON | 0.23Ω typical (HS+LS) - enables high efficiency (>92% typical at 24V/2A) and minimal self-heating. |
| Microstep Resolution | Up to 256 microsteps per full step - achieved via internal sine-table DAC and MicroPlyer interpolation. |
| Chopper Modes | StealthChop2 (ultra-silent) + SpreadCycle (high-dynamic) - selectable via CFG pins; no SPI required. |
| Diagnostic Outputs | ERROR (open-drain fault flag), INDEX (coil B microstep-0 pulse), OV (overvoltage alert) - enable autonomous system monitoring. |
Pinout & Package
The TMC2210AUU+T is packaged in a thermally enhanced 5mm × 5mm TQFN32 (package code T3255+5C) with exposed pad (EP = GND) for optimal heat dissipation (θJA = 29°C/W on four-layer board). Pinout is defined for the TQFN variant per Analog Devices datasheet Rev 2 (April 2024).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1A / OUT2A / OUT1B / OUT2B | H-Bridge motor phase outputs | Drive A/B coils of bipolar stepper; each pair forms one full H-bridge; rated for 36V, 3A peak. |
| STEP / DIR | Digital motion command inputs | Edge-triggered (rising STEP), level-sensitive DIR; internally filtered (10ns spike rejection); compatible with standard motion controllers. |
| IREF | Analog current reference input | Connects external resistor to GND; sets full-scale current (IFS = 1A–3A) with ±5% regulation accuracy. |
| ERROR / INDEX / OV | Open-drain diagnostic outputs | ERROR asserts low on OCP/thermal/UVLO; INDEX pulses at coil B microstep-0; OV signals overvoltage event (fixed threshold). |
| CFG0–CFG7 | Configuration select inputs | Eight digital inputs defining microstep resolution, chopper mode, current scaling, and decay behavior - no firmware or SPI needed. |
| SLEEPN / DRV_ENN | Power control inputs | SLEEPN (active-low) disables logic and analog blocks; DRV_ENN (active-low) floats all motor outputs - both support fast wake-up (2.5ms). |
Key Features
| Feature | Design Value |
|---|---|
| StealthChop2 chopper algorithm | Eliminates audible motor noise and torque ripple at standstill and low speeds - critical for office automation and medical devices. |
| Integrated lossless current sensing (ICS) | Removes need for external sense resistors - saves >15mm² PCB area and eliminates 1–2W power loss per bridge. |
| MicroPlyer step interpolation | Converts coarse step inputs (e.g., 16-step) into smooth 256-microstep motion - preserves legacy controller compatibility while upgrading motion quality. |
| Thermally optimized TQFN32 package | θJA = 29°C/W (four-layer board) enables 2.1ARMS continuous drive without heatsink in space-constrained designs. |
| Configurable protections | Programmable OCP thresholds (1.67A/3.33A/5.0A), UVLO (3.9V), thermal shutdown (165°C), and short-to-GND detection - reduces external protection components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stepper motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMC2209-TA | Same StealthChop2/SpreadCycle engine but lacks INDEX output and has lower max IFS (2.8A vs 3.0A); TSSOP28 only. | No hardware-based homing reference pulse - requires external encoder or software-based stallGuard2 for position recovery. | Choose when board space permits TSSOP28 and INDEX is unnecessary; lower cost for basic S/D motion. |
| DRV8825PWPR | External sense resistors required; no StealthChop2; fixed 32-step max microstepping; higher RON (0.52Ω typical). | Louder operation, larger PCB footprint, and reduced thermal margin - unsuitable for noise-sensitive or miniaturized designs. | Choose only for legacy designs already using DRV8825 layout; not recommended for new low-noise or high-efficiency applications. |
Compared with TMC2209-TA and DRV8825PWPR, the TMC2210AUU+T uniquely combines INDEX pulse generation, 256 microsteps, lossless sensing, and TQFN32 thermal performance - making it the only option supporting silent, encoderless homing in space-constrained industrial motion.

FAQ
What is the maximum continuous RMS current the TMC2210AUU+T can deliver per H-bridge?
The TMC2210AUU+T delivers up to 2.1ARMS per H-bridge at 25°C on a four-layer PCB with adequate copper pour. This value decreases with rising ambient temperature or reduced thermal mass - actual design current must be validated using θJA = 29°C/W and junction temperature limits (TJ ≤ 165°C). The TMC2210AUU+T datasheet provides derating curves for varying PCB stack-ups.
Does the TMC2210AUU+T require an external microcontroller to configure microstepping or chopper mode?
No. The TMC2210AUU+T uses eight dedicated CFG pins (CFG0–CFG7) for hardware-only configuration of microstep resolution (up to 256), chopper mode (StealthChop2 or SpreadCycle), current scaling, and decay behavior. No SPI interface, firmware, or external MCU is needed - simplifying BOM and reducing system latency.
How does the INDEX output function on the TMC2210AUU+T, and what is its timing relationship to motor position?
The INDEX pin on the TMC2210AUU+T is an open-drain output that pulses once per electrical revolution of coil B, aligned precisely to the positive zero-crossing of the microstep sine wave. This provides a hardware-based homing reference without external sensors - enabling repeatable mechanical zeroing in printers, ATMs, and lab instruments. The TMC2210AUU+T generates this pulse autonomously.
Can the TMC2210AUU+T operate from a 5V-only supply, or does it require separate motor and logic rails?
The TMC2210AUU+T requires two supplies: VS (4.5V–36V) for motor power and VCC_IO (2.2V–5.5V) for logic-level definition. It includes an internal 1.8V LDO (VDD1V8) for analog circuitry. A 5V source can serve as VCC_IO, but VS must be ≥4.5V - so 5V-only operation is insufficient for motor drive. The TMC2210AUU+T cannot drive motors from 5V VS.
What thermal management considerations apply to the TMC2210AUU+T in a TQFN32 package?
The TMC2210AUU+T TQFN32 package relies on its exposed pad (EP = GND) for heat transfer. Designers must connect EP to a large internal/external ground plane using ≥6 thermal vias (0.3mm diameter, 0.6mm pitch). With this, θJA drops to 29°C/W (four-layer board), enabling 2.1ARMS continuous operation. Insufficient copper or via count will cause premature thermal shutdown - verify layout against land pattern 90-0013.
