The TMC457 is a stepper and piezo motor servo controller with S-shaped ramps for laboratory automation, 3D-printing, scanners and other automated equipment applications. The device is usable as a trapezoidal ramp generator. Furthermore the TMC457 is powered by ADI Trinamic ChopSync™ technology. The device is designed for an operating voltage of 1.5V and 3.3V. The TMC457 provides a SPI controller and SPI, S/D driver interface. Additionally it has an a/b/n incremental encoder interface.
Applications:
- Medical and laboratory equipment with high-speed motion e.g., for liquid handling
- High end placement and positioning systems / High reliability drives
- Sub-micrometer positioning (piezo motors)
- Active stabilization with incremental encoder and fast PID regulator
