The Allegro ACS781xLR is a fully integrated, automotive-grade Hall-effect-based current sensor IC designed for high-precision measurement of bidirectional AC and DC currents up to 100 A. It features a core-less, low-profile package with a small footprint, offering ultra-low power loss due to its 200 internal conductor resistance. The device provides an analog output voltage (VOUT) that varies linearly with the primary current (IP). Enhanced by common-mode field rejection and Allegro's proprietary integrated shield technology, it delivers superior immunity to interfering magnetic fields and high dV/dt signals, ensuring stable performance in high-side, high-voltage applications. Factory-programmed sensitivity and quiescent output voltage, along with chopper-stabilized signal paths and digital temperature compensation, contribute to its exceptional accuracy and stability across a wide operating temperature range. Ideal for applications requiring precise current monitoring in automotive and industrial environments.
