Fully Integrated, Hall Effect-Based Linear Current Sensor With 2.1 KVRMS Voltage Isolation And A Low-Resistance Current Conductor

The Allegro ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and Communications systems. The device package allows for easy implementation by the customer. Typical applications include Motor Control load detection and management, switched-mode power supplies, and overcurrent fault protection.
The device consists of a precise, low-offset, linear Hall Sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy after packaging.
