The Broadcom® ACHL-7345xT is a fully integrated Hall-effect based isolated linear current sensor device that is designed for AC or DC current sensing in automotive applications. The ACHL-7345xT 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 that the Hall IC converts into a proportional voltage.
Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer.
