Product Introduction

TMC2208 is an ultra-quiet two-phase stepper motor drive chip, continuous drive current 1.4A, peak current 2A, voltage range 4.75V-36V, 256 subdivision. The flexible microPlyer interpolation unit provides up to 256 subdivisions, allowing perfect sinusoidal control even in systems with limited pulse frequencies; these are also designed because stealthChop2 ultra-quiet technology is widely used in 3D printing. Compatible with existing 3D printer electronics, eliminating the expensive costs of redesign. With a standard step/dir interface, it is easy to use. It can replace the original TMC2100, lower heat, especially for 3D printing market.

 

Features:

  • UART configuration interface (9600-500k Baud)
  • Power tube built-in drive current 1.4A ,peak current 2A, voltage range 4.75V-36V
  • Up to 256 native microsteps (without interpolation)
  • CoolStep ™ current dynamic adjustment technology, can save 70% of the energy
  • stealthChop2 - faster motor acceleration/deceleration than stealthChop
  • dcStep ™, stallGuard2 ™ stall detection technology
  • Automatic stealthChop and spreadCycle switchover depending on velocity
  • Hardware compatible with StepStick and Pololu A4988 Stepper Driver
  • Components on bottom PCB side for better heat emission
  • Automatic standby current reduction
  • SteaClthhop mute technology
  • spreadCycle - highly dynamic motor control chopper
