Contractor circuit

Products and reference designs

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.

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.
