TMC4361A DATASHEET
TMC4361A Document Revision 1.10 • 2016-NOV-10
SHORT SPEC
The S-ramp and sixPoint™ ramp motion controller for stepper motors is optimized for high
velocities, allowing on-the-fly changes. TMC4361A offers SPI and Step/Dir interfaces, as well
as an encoder interface for closed-loop operation.
NOTE:
 TMC4361A is a product upgrade of TMC4361.
