Current Sensors

Allegro Microsystems Current Sensors are advanced ICs that achieve high efficiency and power density in designs. The Current Sensors are fully integrated solutions designed to make design-in easy. Allegro’s current sensors include fast over-current detection in addition to a precision analog output. Additionally, the current sensors offer a high voltage with excellent isolation ratings of up to 1100Vrms. The devices are ideal for residential and industrial solar inverter applications.
