DESCRIPTION The Allegro ACS781xLR is a fully integrated current sensor linear IC in a new core-less package designed to sense AC 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 interfering magnetic fields generated by nearby current carrying conductors. The device consists of a precision, low-offset linear Hall circuit 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 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 electric fields, offered by Allegro proprietary integrated shield technology for low-output voltage ripple and low-offset drift in high-side, high-voltage applications. The output of the device has a positive slope (>VCC/2) when an increasing current flows through the primary copper conduction
