Contractor circuit

Block diagram


Our integrated circuits and reference designs help you create reliable and high-performing contractor circuits for switching loads such as motors, HVAC, lighting and heating to a power supply.

Design requirements

Innovative contractor circuit designs often require:

  • Monitoring current and temperature faults to drive solenoid relays or motor drives.
  • Highly efficient architecture to power from 1/3-phase AC or auxiliary DC supply.
  • Adjustable trip timing settings and diagnostics to detect stuck actuators.
