TMC429-I Integrated Circuit Chip Triple Axis Stepper Motor Controller SPI Interface QFN 32

The TMC429-I is a triple axis motion controller that generates the ramped STEP and DIR signals for three stepper axes from a single SPI controlled device.

Positioning is handled with on chip ramp generation, including acceleration, deceleration and microstep frequency scaling, so the host only writes target positions and velocities.

Each axis can drive a separate driver stage, and the SPI interface also programs the connected driver chips, which keeps the microcontroller pin count low in multi axis systems.

Supplied in a QFN-32, the parts ship as new stock with full traceability, are RoHS compliant and lead free, and samples plus volume pricing are available on request.
