Mobile robot motor control

Block diagram

Overview

Our integrated circuits and reference designs help you create a compact, efficient and fully protected power stage module for mobile robots. Our analog and embedded processing products enable improved motor control performance and support functional safety requirements.

Design requirements

  • Small form factor gate drivers enabling high-power density power stage.
  • Precise current and voltage sense for accurate position and torque control.
  • Reliable overcurrent protection against short circuit and shoot through events.
  • Efficient non-isolated power supplies with tight regulation.
