Product details
Overview
TMC2210AUU+ from Analog Devices is a standalone 2-phase stepper motor driver IC with integrated H-bridges, pin-configurable step/direction interface, and StealthChop2 silent operation. It delivers up to 3.0A full-scale current per bridge, supports 256 microsteps, and operates from 4.5V to 36V supply - enabling compact, low-noise motion control in space-constrained printers and ATM mechanisms.
For engineers reviewing the TMC2210AUU+ datasheet, TMC2210AUU+ pinout, TMC2210AUU+ application, or TMC2210AUU+ equivalent, this page provides verified package mapping (TQFN32 5×5 mm), confirmed thermal performance (θJA = 29°C/W on 4-layer PCB), validated diagnostic outputs (ERROR, INDEX, OV), and real-world current regulation behavior across CFG pin configurations.
Technical Context
The TMC2210AUU+ implements dual fully integrated 36V H-bridges with non-dissipative current sensing (ICS), eliminating external sense resistors. Its chopper architecture supports both StealthChop2 (ultra-quiet, fixed-frequency PWM) and SpreadCycle (dynamic cycle-by-cycle current control) modes, selectable via CFG pins.
Configuration is entirely pin-driven: microstep resolution (up to 256), run/hold current scaling, chopper mode, and overcurrent threshold are set using eight CFG inputs. The internal 1.8V LDO powers logic circuitry, while a charge pump generates gate drive voltage for high-side FETs without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5V to 36V DC - supports wide-input industrial and automotive power rails without external regulators. |
| Max RMS Current per Bridge | 2.1A RMS at 25°C on 4-layer PCB - defines continuous torque capability under thermal equilibrium. |
| Full-Scale Current Setting | 3.0A peak (IFS), set by external IREF resistor - determines maximum current regulation limit of embedded DAC. |
| Total RON (HS + LS) | 0.23Ω typical - enables >90% driving efficiency and minimal self-heating at rated load. |
| Microstep Resolution | 256 microsteps per full step - achieved via on-chip sine table and MicroPlyer interpolation for smooth low-speed motion. |
| StealthChop2 Frequency | 22–28 kHz (configurable) - places switching noise above human hearing range for silent operation. |
| Thermal Shutdown Threshold | 165°C junction temperature - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
The TMC2210AUU+ is packaged in a thermally enhanced TQFN32 (5 mm × 5 mm, 0.5 mm pitch) with exposed pad (EP = GND) for efficient heat dissipation. Pin count and layout match the TQFN32 footprint defined in land pattern 90-0013.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1A / OUT2A / OUT1B / OUT2B | H-Bridge motor outputs | Drive two-phase bipolar stepper coils; each pair forms one complete H-bridge with integrated FETs. |
| STEP / DIR | Digital motion command interface | Rising-edge-triggered STEP with synchronous DIR polarity - compatible with standard motion controllers and FPGA step generators. |
| IREF | Analog current reference input | Connects external resistor to GND to set full-scale current (IFS = 1–3 A); voltage at pin is fixed at 0.9 V. |
| ERROR / INDEX / OV | Open-drain diagnostic outputs | Active-low ERROR flags fault conditions; INDEX pulses at coil B zero-crossing; OV indicates overvoltage event. |
| CFG0–CFG7 | Configuration inputs | Eight digital inputs that define microstep resolution, chopper mode, current scaling, and protection thresholds - no SPI/I²C required. |
| DRV_ENN | Enable control input | Active-high signal disables all H-bridges and places outputs in high-impedance state - used for emergency stop or power gating. |
| SLEEPN | Low-active sleep/reset input | Pulls device into ultra-low-power mode (<18 μA); also resets internal registers and re-reads CFG pins on wake-up. |
Key Features
| Feature | Design Value |
|---|---|
| StealthChop2 silent operation | Eliminates audible motor noise and mechanical resonance during standstill and low-speed motion via optimized PWM timing. |
| Integrated lossless current sensing | Replaces bulky external shunt resistors with on-chip sensing - saves >5 mm² PCB area and removes 1–2 W of dissipation. |
| MicroPlyer step interpolation | Accepts coarse step inputs (e.g., 1/16-step) and interpolates internally to true 256-microstep resolution - preserves controller simplicity. |
| Configurable overcurrent protection | OCP threshold adapts to selected current range (1.67 A / 3.33 A / 5.0 A) via CFG2/CFG3 - avoids false trips during acceleration transients. |
| Thermally optimized package | TQFN32 with exposed pad achieves θJA = 29°C/W on 4-layer board - enables 2.1A RMS operation without heatsink in most layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stepper driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMC2209-LA | Same pinout and feature set but uses SPI configuration instead of pin-strapping; lower max IFS (2.8A vs 3.0A). | Requires MCU firmware support for register programming; lacks native STEP/DIR fallback mode. | Choose when system already uses SPI bus and needs runtime parameter adjustment. |
| DRV8825PWPR | Fixed 32-step microstepping (no interpolation); higher RON (0.42Ω); no integrated current sensing. | Needs external sense resistors and additional filtering; limited to basic open-loop motion. | Choose for cost-sensitive, low-performance applications where silent operation is not required. |
Compared with TMC2210AUU+, the TMC2209-LA offers greater configurability at the cost of MCU dependency, while the DRV8825PWPR trades integration and noise performance for lower unit cost - making TMC2210AUU+ optimal for space-constrained, low-noise, pin-configurable designs.

FAQ
What is the maximum continuous current the TMC2210AUU+ can deliver per H-bridge?
The TMC2210AUU+ supports a maximum RMS current of 2.1A per H-bridge at room temperature on a four-layer PCB. This value is thermally limited - actual achievable current depends on PCB copper area, ground plane thickness, airflow, and heatsinking. At 3.0A full-scale setting (IFS), peak current reaches 5.0A, but RMS must remain ≤2.1A to avoid thermal shutdown.
Does the TMC2210AUU+ require external current sense resistors?
No, the TMC2210AUU+ features fully integrated non-dissipative current sensing (ICS), eliminating the need for external shunt resistors. Current measurement is performed internally using MOSFET RDS(ON) monitoring, reducing PCB area, power loss, and calibration drift - a key differentiator from legacy drivers like the DRV8825.
How does StealthChop2 in the TMC2210AUU+ achieve silent motor operation?
StealthChop2 in the TMC2210AUU+ uses adaptive PWM frequency modulation and optimized blanking time to suppress audible noise and mechanical resonance. It operates in the 22–28 kHz range - above human hearing - while maintaining precise current regulation and torque consistency at standstill and low speeds.
Can the TMC2210AUU+ be configured without a microcontroller?
Yes, the TMC2210AUU+ is designed for pin-configuration only: all critical parameters - microstep resolution (up to 256), chopper mode (StealthChop2/SpreadCycle), current scaling, and protection thresholds - are set using eight CFG pins. No SPI, UART, or firmware is required, simplifying integration in MCU-free or resource-constrained systems.
What package type is used for the TMC2210AUU+ and why does it matter?
The TMC2210AUU+ uses the TQFN32 (5 mm × 5 mm) package with an exposed thermal pad. This package achieves θJA = 29°C/W on a four-layer board - significantly better than alternatives like TSSOP - enabling higher continuous current (2.1A RMS) without external heatsinks. The small footprint also supports miniaturized motion modules in printers and ATMs.
