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. Housed in a low-profile, core-less package with a small footprint, it offers high precision and excellent performance in demanding applications. The device features integrated shielding for immunity to dV/dt and stray electric fields, common-mode field rejection, and factory-programmed calibration for optimized accuracy. Its 200 internal conductor resistance minimizes power loss, while its monolithic design ensures high reliability. Ideal for high-side, high-voltage applications, the ACS780xLR provides an analog output voltage proportional to the primary current.
