Allegro Microsystems (ACS713ELCTR-20A-T) Current Sensor, Voltage Isolation

Current Sensor, Voltage Isolation, 80 kHz, SOIC, 8 Pins, 4.5 V, 5 V Product Overview The ACS713ELCTR-20A-T is a fully integrated, hall effect-based linear Current Sensor IC. It provides economical and precise solutions. The device package allows for easy implementation by the customer. 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 Becomes Hall IC, which is programmed for accuracy after packaging. The output of the device has a positive slope (>VIOUT(Q)) when an increasing current flows through the primary copper conduction path (from pins 1 and 2, to pins 3 and 4), which is the path used for current sensing.
