Product Information

Back to top
The TMC429 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 (64 μsteps / fullstep) 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 cost-effective and highly competitive solutions.

Applications:
• CCTV, Security
• Antenna Positioning
• Heliostat Controller
• Battery powered applications
• Office Automation
• ATM, Cash recycler, POS
• Lab Automation
• Liquid Handling
• Medical
• Printer and Scanner
• Pumps and Valves

Symmetry Electronics is an authorized Trinamic distributor.
