- About Allegro
Allegro’s integrated Hall current sensor portfolio provides the world’s most compact current sensing solutions with embedded high voltage isolation for motor control, power conversion and management, technologies that are critical to modern refrigerator’s energy efficiency, safety and comfort requirements.
Allegro's current sensor ICs can be used in almost every application in a motor control application as referenced in the accompanying block diagram.
CS1, CS2 and CS3: High and low side phase current sensing for compressor/fan motor control applications. Recommended current sensors include ACS712, ACS710, ACS756 and ACS758, depending on the required current sensing range. Integrated over-current fault detection is available on the ACS710 device.
CS4, CS5 and CS6: Current sensors for power conversion/management, power factor correction (PFC) and current monitoring applications. Recommended current sensors with high bandwidth, high isolation voltage and OC fault output include ACS756, ACS758 and ACS710.
