Overview

Our integrated circuits and reference designs help you create alternating current (AC) drive communication modules for safe, secure and reliable communication links to external programmable logic controllers (PLCs).

Design requirements

AC drive communication modules often require:

  • Flexibility to execute a variety of industry standards and proprietary protocols.
  • Support for different real-time protocol stacks.
  • Low-latency, low-bit-error, EMC immune interfaces.
  • High-efficiency, sequenced and supervised voltage rails for reliable operation.
