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.
