TMC2208 is an ultra quiet two-phase stepper motor driver chip, continuous driver current 1.4 A, peak current 2 A, voltage range 4.75 V-36 V, 256 subdivision.

The flexible microplyer interpolation unit offers up to 256-subdivisions, enabling perfect sine control even in systems with limited pulse frequencies; faster engine acceleration/deceleration than StealthChop, these were also developed because the ultra-quiet StealthChop2 technology is widely used in 3D printing.

Compatible with existing 3D printer electronics. With a standard step/dir interface, it is easy to use. It can replace the original TMC2100 A4988 DRV8825 LV8729.

Main features: UART configuration interface, CoolStep technology for dynamic adjustment of current, can save 70% of energy; dcStep, stallGuard2 stable detection technology, components on the bottom of the PCB for better heat dissipation; Automatic standby power reduction.

Specifications

#Interface: Step/You

1. Configuration: CFG pins or UART

2. Native microsteps: up to 1/256

3. MicroPlyer microsteps: 1/256

4. Logic voltage (VIO): 3-5 V

5. Motor voltage (VM): 4,75-36 V

6. Motor phase current max.: 1.2 A RMS, 2.0 A tip. Therefore, the reference voltage of the driver module should not exceed 1 V. At the same time, the driver module must be dissipated, otherwise it will affect the service life of the driver module.

7. Internal V controller: enabled

8. RDSon: ¡Ü0.3 Ohm

9. StealthChop (silent): yes

10. SpreadCycle: Yes

11. MicroPlayer

12. CoolStep: No

13. StallGuard: No

14. DcStep: No

Note:

1.The TMC2208 driver needs an additional fan to cool it, otherwise it can be destroyed by the high temperature.

2.Do not connect the motor when measuring the voltage, otherwise the driver may be easily burned.

3.When measuring the voltage, the power supply should be connected, do not just connect the USB power supply.

4. Please pay special attention to the directions!
