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.
