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
