ADI Trinamic TMC2209-LA Motor Driver IC

Analog Devices TMC2209-LA Motor Driver IC is designed for two-phase stepper motors with up to 2.8A coil-current (peak) and 2ARMS phase-current handling capabilities. This ultra-silent motor driver IC exhibits voltage-chopper-based proprietary StealthChop2™ silent-drive technology to ensure noiseless operation, maximum efficiency, and best motor torque. The TMC2209 Motor Driver also offers technologies like SpreadCycle™ and StallGuard4™ for high-precision cycle-by-cycle current control and sensorless homing respectively. This device covers various applications, from battery systems to embedded applications with up to 2A motor current per coil. The TMC2209-LA Motor Driver is ideally suited for 3D printers, POS, office and home automation, textiles sewing machines, CCTVs, security, ATMs, HVAC, and battery-operated equipment.

Features

  • 2-phase stepper motors with up to 2.8A coil current (peak) and 2ARMS
  • STEP/DIR interface with 8, 16, 32, or 64 micro-step pin setting
  • Low RDSon, low heat-up at LS 170mΩ and HS 170mΩ (typical at 25°C)
  • 4.75VDC to 29VDC voltage range 
  • Low power standby to fit standby energy regulations
  • Internal sense resistor option (no sense resistors required)
  • Passive braking, freewheeling, and automatic power down
  • Single wire UART and OTP for advanced configuration options
  • Integrated pulse generator for standalone motion
  • Full protection and diagnostics
  • Compact 28QFN (5mm x 5mm) package with a large heat slug
  • Key technologies:
    • StealthChop2™:
      • No noise high-precision chopper algorithm for inaudible motion and inaudible standstill of the motor
    • MicroPlyer™:
      • Microstep interpolator for obtaining full 256 micro-step smoothness with lower resolution step inputs starting from full-step
    • SpreadCycle™:
      • High-precision cycle-by-cycle current control for the highest dynamic movements
    • StallGuard4™:
      • Sensorless homing safes end switches and warn in case of motor overload
    • CoolStep™:
      • Uses StallGuard measurement in order to adapt the motor current for best efficiency and lowest heat-up of motor and driver
