Description
Description:1. TMC2208 is an ultra-quiet two-phase stepper motor driver chip, continuous drive current 1.4A, peak current 2A, voltage range 4.75V-36V, 256 subdivision; with patented technology spreadCycle (high dynamic chopper) ), stealthChop2 (ultra-quiet technology), microPlyer (subdivision control).2. The flexible microPlyer interpolation unit can provide up to 256 subdivisions, which can perfectly realize sinusoidal control even in systems with limited pulse frequency; because the stealthChop2 ultra-quiet technology is widely used in 3D printing, these components are The design is also compatible with the existing 3D printer electronics, eliminating the expensive cost of redesign. With standard step/dir interface, it is simple and convenient to use.
Features:
Subdivision up to 256;Will not lose step when driving with high load;The logics interface level is: 3-5V;Input voltage range: 4.75-36V DC;The subdivision mode can be 2, 4, 8, 16 subdivision;
In the traditional stepping motor drive scheme, there will be an excessive current, or current dead zone, when the current crosses the zero point. At this time, there is no current in the motor coil. This is one of the main factors that cause the motor to vibrate. SpreadCycle guarantees that the stepper motor has a smooth transition at the zero-crossing point and no dead-zone current. There is almost no jitter when using TMC2208 several stepper motor drive chips;
SpreadCycle PWM chopping mode automatically configures a hysteresis attenuation function between slow and fast attenuators. The average current reflects the configured normal current. There will be no transition period when the sine wave crosses the zero point. This reduces the fluctuation of current and torque, and makes the current waveform closer to the sine wave. Compared with the traditional constant chopping type, SpreadCycle PWM chopping The motor under wave mode control runs more smoothly and smoothly.
Package Includes:
1 x Stepper Motor Driver Module
