PLC circuit breakers

Block diagram


Our integrated circuits and reference designs enable designers to build programmable logic control (PLC) circuit breaker modules, enabling overvoltage and overcurrent limits which are configurable to prevent disturbances to the system.

Design requirements

PLC circuit breaker designs often require:

  • ORing and hot-swap functions to protect the input and output power rails.
  • Current and voltage sensing to allow fast reacting electronic fuse functions.
  • Backplane communication to allow exchange of data with the control system.
