Allegro MicroSystems 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.
The Allegro Microsystems Current Sensors offer a comprehensive portfolio including -
0A to 50A Integrated Current Sensor ICs
Fully integrated, high isolation current sensor solutions provide accurate measurement with very low resistance—all without the need for external isolation components.
0A to 400A Integrated Current Sensor ICs
High current sensor IC packages are fully integrated solutions that provide high accuracy and reliability. These sensors are automotive-grade devices that can take the heat and deliver highly accurate open-loop current sensing in the harshest applications environments.
Field Sensors 0A to >1000A Sensor ICs
Customer-programmable for offset and sensitivity, these Hall linear ICs are packaged in a 1mm thick KT package SIP that is often used in applications with a ferromagnetic core and designed to sense currents above 1500A.
