100 Amp Bidirectional Linear Hall Effect Current Sensor ALLEGRO ACS780LLRTR-100U-T with Programmed Sensitivity

Product Overview

The Allegro ACS780xLR is a fully integrated, automotive-grade linear Hall-effect current sensor IC designed for bidirectional AC and DC current sensing up to 100 A. It features a core-less, low-profile package with a small footprint and offers high-precision measurement with an ultra-low 200 internal conductor resistance for minimal power loss. The device incorporates common-mode field rejection and proprietary integrated shield technology for enhanced immunity to interfering magnetic fields and high dV/dt signals, ensuring stable performance in high-side, high-voltage applications. Its factory-programmed sensitivity and quiescent output voltage, along with chopper-stabilized signal path and digital temperature compensation, contribute to excellent accuracy and stability across its operating temperature range. The ACS780xLR is ideal for applications requiring precise current monitoring in automotive and industrial environments.
