TMC2209 Stepper Motor Treiber

StealthChop is an extremely quiet mode of operationfor stepper motors. It is based on a voltage  mode  PWM.  In  case  of  standstill  and  at  low  velocities,  the  motor  is  absolutely noiseless.  Thus, StealthChopoperated  stepper  motor  applications  are  very  suitable  for indoor  or  home  use.  The  motor  operates  absolutely  free  of  vibration  at  low  velocities. With StealthChop, the motor current is applied by driving a certain effective voltage into the coil, using a voltage mode PWM. With the enhanced StealthChop2, the driver automatically adapts to the application for best performance. No more configurations are required. Optional configuration allows for tuning the setting in special cases, or for storing initial values for the automatic adaptation algorithm.For high velocity considerSpreadCyclein combination with StealthChop.
