3.3V HIGH-CURRENT/HIGH- TEMPERATURE LINEAR HALL-EFFECT CURRENT SENSOR ICS

摘要

The new ACS759 from Allegro Microsystems is a high-current/high-temperature linear Hall-effect current sensor IC that provides an economical and precise solution for AC or DC current sensing in 3.3V supply applications. The device consists of a precision, low-offset linear Hall sensor circuit with a copper conduction path located near 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 voltaqe.
