1、Product Introduction
1、TMC2209 is an ultra-silent motor driver IC for two-phase stepper motors. Its
continuous drive current is 2A and peak current is 2.8A. Compared with TMC2208,
the driving current of this IC is not only improved by 0.6a-0.8a, but also this IC
increases the function of locked-motor test.
2、Voltage Range : 4.75V - 28V DC
This IC have some patent technologies:
SpreadCycle™ (highly dynamic motor control chopper)
StealthChop2™ (ultra-quiet technology)
MicroPlyer™ (microstep control)
StallGuard4™ (locked-motor test)
CoolStep™ (current dynamic control)
3 、 The Flexible microPlyer interpolation unit can provide 256 microsteps.
Stallguard4™locked-motor test can provide an abnormal signal when the motor
rotates abnormally. CoolStep™ current dynamic control can save 75% energy. The
sinusoidal control can be perfectly realized even in the system with limited pulse
frequency. Since stealthChop2 ™ ultra-quiet technology is widely used in 3D
printing, the design of these components is also compatible with existing 3D
printer electronic devices, and it eliminates the expensive cost of redesigning.The
module has a standard step/dir interface, it's easy to use.
