DESCRIPTION
The TMC4361 is intended for applications
where a fast and jerk-limited motion profile
is desired. This motion controller adds to
any microcontroller with SPI interface. It
supports S-shaped, trapezoid, and rectangle
ramps. With encoder, the TMC4361 allows
for an extremely quick and precise
positioning. Its servo features include no
step-loss, energy efficiency, and target
positioning with oscillation-free algorithms.
Standard SPI and STEP/DIR interfaces to the
motor driver simplify communication.
High end features without software effort
and small form factor enable miniaturized
designs with low external component
count for cost-effective and highly
competitive solutions.
