Product details
Overview
TMC2210ATJ+T from Analog Devices is a standalone 2-phase stepper motor driver IC with integrated H-bridges, pin-configurable step/direction interface, 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 with StealthChop2 silent operation-enabling precise, low-noise motion control in compact 3D printer and office automation systems.
For engineers reviewing the TMC2210ATJ+T datasheet, TMC2210ATJ+T pinout, TMC2210ATJ+T application, or TMC2210ATJ+T equivalent, key selection criteria include thermal performance on four-layer PCBs, CFG-pin configuration for chopper mode and current scaling, diagnostic output behavior (ERROR/INDEX/OV), and compatibility with S/D-based motion controllers requiring microstep interpolation and standstill detection.
Technical Context
The TMC2210ATJ+T implements dual fully integrated 36V H-bridges with typical total RON of 0.23Ω (HS+LS), enabling high-efficiency motor drive with minimal self-heating. Its internal 1.8V LDO powers logic circuitry, while a charge pump generates VCP for gate driving, supporting robust MOSFET switching across the full 4.5V–36V supply range.
StealthChop2 and SpreadCycle chopper modes are selected via CFG pins; StealthChop2 provides noiseless operation at lower speeds, while SpreadCycle delivers high-dynamic torque response. MicroPlyer interpolates coarse STEP inputs into smooth 256-microstep waveforms without host CPU overhead-critical for resource-constrained embedded motion controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5V to 36V DC - supports wide-input industrial and battery-backed motion systems without external regulators. |
| Max RMS Current per Bridge | 2.1ARMS at 25°C on four-layer PCB - defines continuous thermal limit under typical layout conditions. |
| Full-Scale Current Setting | 3.0A peak (IFS) set by external IREF resistor - enables precise current regulation without sense resistors. |
| Microstep Resolution | Up to 256 microsteps per full step - achieved via on-chip sine table and MicroPlyer interpolation. |
| Total H-Bridge RON | 0.23Ω typical (HS + LS) - minimizes conduction loss and board-level heat dissipation. |
| Operating Temperature | −40°C to +125°C ambient - qualified for industrial and automotive-adjacent environments. |
| Package Type | TQFN32 5mm × 5mm with exposed pad - optimized for thermal transfer and space-constrained PCBs. |
Pinout & Package
TMC2210ATJ+T is housed in a thermally enhanced TQFN32 (5mm × 5mm) package with exposed die pad (EP = GND). The package supports high-power density designs via low θJA = 29°C/W on four-layer boards and requires ≥6 vias under EP for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1A / OUT2A / OUT1B / OUT2B | H-Bridge motor outputs (Phase A/B high/low sides) | Direct connection to stepper coil terminals; each pair drives one phase with integrated FETs and current sensing. |
| STEP / DIR | Digital motion command inputs | Rising-edge-triggered STEP with DIR polarity control; internally filtered for noise immunity and synchronized to 12.5MHz clock. |
| IREF | Analog reference input for current scaling | External resistor to GND sets full-scale current (IFS); supports 1A–3A range with ±5% regulation accuracy. |
| ERROR / INDEX / OV | Open-drain diagnostic outputs | ERROR asserts low on fault (OCP, UVLO, thermal shutdown); INDEX pulses at coil B zero-crossing; OV indicates overvoltage event. |
| DRV_ENN / SLEEPN | Power-stage enable and sleep control | Active-high DRV_ENN disables H-bridges (three-state); active-low SLEEPN reduces quiescent current to 4μA and resets configuration registers. |
| VCP / CPO / CPI | Charge pump voltage generation | VCP supplies gate drive; CPO/CPI form external 22nF capacitor network to boost high-side FET turn-on voltage above VS. |
Key Features
| Feature | Design Value |
|---|---|
| StealthChop2 chopper mode | Eliminates audible motor noise and vibration during low-speed operation and standstill via adaptive PWM frequency modulation. |
| SpreadCycle current control | Delivers high-torque, dynamic response during acceleration/deceleration using cycle-by-cycle current regulation and fast decay timing. |
| MicroPlyer step interpolation | Converts 1–16 microstep STEP inputs into smooth 256-microstep motion profiles without host processor intervention. |
| Integrated lossless current sensing (ICS) | Replaces external shunt resistors, saving >75% PCB area and eliminating power loss associated with sense resistors. |
| Comprehensive protection suite | Includes overcurrent (OCP), thermal shutdown (165°C), undervoltage lockout (UVLO), short-to-GND, and overvoltage detection (OV). |

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 pinout, identical feature set, but rated for 2.0ARMS (vs. 2.1ARMS) and uses smaller TQFN28 package; lacks TSSOP38 option. | Better suited for ultra-compact designs where thermal margin is less critical; not recommended for sustained 2.1A loads. | Select TMC2209-TA only when board space is constrained and peak RMS current remains ≤2.0A. |
| DRV8825PWPR | Requires external current-sense resistors; no StealthChop2 or MicroPlyer; max 2.2A peak but only 1.75ARMS typical; larger thermal footprint. | Lower BOM cost but higher PCB area and acoustic noise; lacks integrated diagnostics and interpolation. | Choose DRV8825PWPR for cost-sensitive, non-noise-critical applications where external sensing and simpler configuration are acceptable. |
Compared with TMC2210ATJ+T, TMC2209-TA offers identical functionality in a smaller footprint but reduced thermal headroom, while DRV8825PWPR trades integration and silence for lower component count and cost-making TMC2210ATJ+T optimal for noise-sensitive, space-constrained, and thermally demanding motion systems.

FAQ
What is the maximum continuous RMS current supported by the TMC2210ATJ+T?
The TMC2210ATJ+T supports a maximum RMS current of 2.1ARMS per H-bridge at room temperature on a four-layer PCB. This value is thermally limited-the actual achievable current depends on PCB copper area, heatsinking, and ambient airflow. For sustained 2.1ARMS operation, use ≥6 thermal vias under the exposed pad and maintain ≥1 oz copper on inner layers.
How does the TMC2210ATJ+T achieve silent motor operation without external components?
The TMC2210ATJ+T achieves silent operation through its proprietary StealthChop2 chopper algorithm, which dynamically modulates PWM frequency to avoid audible resonance bands. Unlike traditional choppers, StealthChop2 requires no external RC networks or tuning-configuration is done entirely via CFG pins or optional SPI interface, and it works with standard stepper motors.
Can the TMC2210ATJ+T be used with a 24V power supply and 5V logic interface?
Yes-the TMC2210ATJ+T accepts VS = 4.5V–36V and supports independent VCC_IO = 2.2V–5.5V, allowing direct interfacing with 3.3V or 5V microcontrollers. The STEP, DIR, and CFG pins are referenced to VCC_IO, while motor outputs swing from VS. No level-shifting circuitry is required.
What diagnostic outputs does the TMC2210ATJ+T provide, and how are they used?
The TMC2210ATJ+T provides three open-drain diagnostic outputs: ERROR (active-low fault flag), INDEX (coil B zero-crossing pulse), and OV (overvoltage indicator). Each requires an external pullup resistor. ERROR signals OCP, thermal shutdown, or UVLO events; INDEX enables homing and synchronization; OV triggers external clamping circuits to protect the supply rail.
Is the TMC2210ATJ+T pin-compatible with other Trinamic drivers like the TMC2208 or TMC2209?
The TMC2210ATJ+T shares the same TQFN32 footprint and core pin assignments (STEP, DIR, IREF, OUTx, etc.) with the TMC2209-TA, enabling drop-in replacement in many layouts. However, it is not pin-compatible with the TMC2208 due to differences in CFG pin count and diagnostic output mapping-always verify pin configuration tables before substitution.
