Allegro Current Sensors Features and Innovations

DC Working Voltage

Our packages have the highest working voltages in SOIC-16 footprint

Overcurrent Detection

Our current sensors include fast overcurrent detection in addition to a precision analog output.

High Speed sensors replace bulky current transformers

High speed integrated sensors are the smart alternative to bulky current transformers (CTs).

Allegro Current Sensors Portfolios

0 to 50 A Integrated Current Sensor ICs

Our family of fully integrated, high isolation current sensor solutions provides accurate measurement with very low resistance—all without the need for external isolation components.

0 to 400 A Integrated Current Sensor ICs

Our high current sensor IC packages are fully integrated solutions that also 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 0 to >1000 A Sensor ICs

Customer-programmable for both offset and sensitivity, these Hall linear ICs are packaged in a 1 mm thick KT package SIP that is often used in applications with a ferromagnetic core and are designed to sense currents above 1500 A.
