ACS712 – 30A Hall Effect-Based Linear Current Sensor – SOIC-8 Package
ACS712-30A (ACS712ELCTR-30A-T) Current Sensor Package 8-SOIC, 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, switch-mode power supplies, and overcurrent fault protection. The device is not intended for automotive applications. The device consists of a precise, low-offset, linear Hall 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 the Hall IC converts into a proportional voltage. Device accuracy is optimized through the
the close proximity of the magnetic signal to the Hall transducer.
