Air Conditioners

Energy efficiency, low noise, ease of use and reliability are required in modern air conditioning units. To accomplish these goals, precise control of compressor and fan motors is required. Speed and phase current sensing provide the necessary feedback signals to the data processing unit and motor controller to achieve optimal system performance. These sensor ICs also allow a rapid detection of fault conditions which could prevent expensive damages to the system. Power consumption can also be enhanced by using current sensors to deliver highly efficient power inverters.

 

Allegro offers a wide selection of speed, position and current sensor ICs. Linear Hall sensor and integrated current sensor ICs provide a non-intrusive, reliable, high precision and low cost measurement. Patented packaging technology of the ACS7XX family offers high levels of isolation and ease of system assembly. Allegro also offers high performance LED drivers and Hall switches and latches that could improve system reliability.
