Allegro MicroSystems Inc. Thermally Enhanced Smd Current Sensor IC ACS781LLRTR-100B-T

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 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 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 conductionpath (from terminal 5 to terminal 6), which is the path used for current sampling. The internal resistance of this conductive path is 200 μΩ typical, providing low power loss. The thickness of the copper conductor allows survival of the device at high overcurrent conditions. The terminals of the conductive path are electrically isolated from the signal leads (pins 1 through 4, and 7), and allows the device to operate safely with voltages up to 100 V peak on the primary conductor. The device is fully calibrated prior to shipment from the factory. The ACS781xLR family is lead (Pb) free. All leads are plated with 100% matte tin, and there is no Pb inside the package. The heavy gauge leadframe is made of oxygen-free copper.
