Circuit breakers

Programmable logic controller (PLC), DCS & PAC - circuit breaker system integrated circuits and reference designs


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

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
