TMC5072-LA

Motor Drivers, Controllers Overview

The TMC5072-LA-T is a dual-axis stepper motor controller and driver IC from Analog Devices Inc./Maxim Integrated. It integrates sophisticated ramp generators, two power stages, and advanced diagnostics in a compact 48-QFN (7x7 mm) package. The device supports bipolar stepper motors with an output current of up to 1.1 A per phase and operates within a supply voltage range of 5.5 V to 26 V. It features high-resolution microstepping up to 1/256 steps and includes interfaces such as SPI, Step/Dir, and UART. The component is designed for precise motion control applications requiring silent operation and efficient energy management.

Motor Drivers, Controllers Procurement Notes

Verify the specific suffix 'LA-T' against official manufacturer documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with required voltage levels and interface signals before integration. Check for moisture sensitivity handling requirements during storage and assembly processes.

Motor Drivers, Controllers Selection Notes

Select this component for applications requiring dual-axis control in a minimal footprint. Consider the 1.1 A continuous current rating and 26 V maximum supply voltage when matching motor specifications. Evaluate the need for SPI or UART interfaces versus simple Step/Dir control based on system complexity.
