DESCRIPTION
The TMC4210 is a 1-axis miniaturized
stepper motor controller with an industry
leading feature set. It controls the motor
via Step/Direction interface. Based on
target positions and velocities - which can
be altered on the fly - it performs all real
time critical tasks autonomously. The
TMC4210 offers high level control functions
for robust and reliable operation. The 4
wire serial peripheral interface allows for
communication with the microcontroller.
Together with a microcontroller the
TMC4210 forms a complete motion control
system. High integration and small form
factor allow for miniaturized designs for
cost-effective and highly competitive
solutions.
