Application 1: The ACS780xLR outputs an analog signal, VOUT, that varies linearly with the bidirectional AC or DC primary

current, IP, within the range specified. CF is for optimal noise management, with values that depend on the application.

ACS780xLR

DESCRIPTION

The Allegro ACS780xLR is a fully integrated current sensor

linear IC in a new core-less package designed to senseAC and

DC currents up to 100 A. This automotive-grade, low-profile

(1.5 mm thick) sensor IC package has a very small footprint.

The Hall sensor technology also incorporates common-mode

field rejection to optimize performance in the presence of

interferingmagneticfieldsgeneratedbynearbycurrent-carrying

conductors.

Thedeviceconsistsofaprecision,low-offsetlinearHallcircuit

with a copper conduction path located near 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 close

proximity of the primary conductor to the Hall transducer and

factory programming of the sensitivity and quiescent output

voltage at the Allegro factory.

Chopper-stabilized signal path and digital temperature

compensation technology also contribute to the stability of the

device across the operating temperature range.

High-level immunity to current conductor dV/dt and stray

electricfieldsisofferedbyAllegroproprietaryintegratedshield

technology, for low-output voltage ripple and low-offset drift

in high-side, high-voltage applications.
