    • IRMS = 4ARMS (6A Full-Scale Sine Wave Peak)
    • IMAX = 9.0A (Bridge Peak Current)
  • SPI for Configuration and Diagnostics
  • Step and Direction Interface for Control
  • Fully-Integrated Lossless Current Sensing
  • Incremental Encoder Interface
  • TriCoder Sensorless Standstill Steploss Detection and Full-Step Encoder
  • Highest Resolution of 256 Microsteps

  • StealthChop+ Silent and Smooth Motor Operation with Resonance Dampening
  • SpreadCycle Highly Dynamic Motor Control Chopper
  • StallGuard2, StallGuard+ Sensorless Load Detection
  • CoolStep, CoolStep+ Current Control for Application Energy Savings up to 90%
  • μDcStep Load Dependent Velocity Adaptation
  • Passive Braking and Freewheeling Mode
  • Chip Temperature and Supply Voltage Measurement
  • Full Protection and Diagnostics
  • Real-Time On-Chip Scope Interface (RT-OCSI)
  • Overvoltage Protection Output
  • Compact 30-Pin 6mm x 6mm FCQFN Package

The TMC2262 is a miniaturized, smart, high-power single axis stepper motor driver IC with step and direction interface, SPI, and extensive diagnostic capabilities. Highest integration, high energy efficiency, and a small form factor enable miniaturized, scalable, and cost-effective motor drive solutions perfectly suited for Nema 17, Nema 23, and even Nema 24 steppers.

StealthChop+ ensures noiseless operation and maximum efficiency, optimal motor torque control, and dampening of mid-range motor resonances for a smoothly running motor with low mechanical vibrations. Combined with StallGuard+, CoolStep+ and μDcStep, this results in a highly efficient and versatile stepper motor driver. An unloaded Nema 17 motor automatically runs with as low as a few 10mA of supply current.

The TMC2262 smart 256 microstep motor driver integrates two 65V, 4.25A RMS, 6A peak H-bridges plus non-dissipative integrated current sensing (ICS). ICS eliminates bulky external sense resistors, resulting in space and power savings.

The integrated power MOSFETs' low impedance of ~40mΩ ensures high efficiency and low heat generation.

Abundant diagnostics include an on-chip scope interface for tuning and checking (RT-OCSI), temperature and voltage ADC, and a full set of protection functions like short protection and thermal shutdown.

It comes in a compact, near chip-scale, thermally optimized 30-pin 6mm x 6mm FCQFN package.
