TMC429-PI24

The TMC429-PI24 is a miniaturized Stepper Motor Controller with an industry leading feature set. It controls up to three motors via SPI or step/direction interface. The SPI interface provides a programmable 6-bit microstep table (64µsteps/full step) for best step accuracy with 2-phase stepper motors. Based on target positions and velocities - which can be altered on the fly - it performs all real time critical tasks autonomously. The TMC429 offers high level control functions for robust and reliable operation. Two separate 4 wire serial peripheral interfaces allow for communication with the microcontroller and with up to three daisy chained stepper motor drivers. Together with a microcontroller the TMC429 forms a complete motion control system. High integration and small form factor allow for miniaturized designs for highly competitive solutions.
