Product Overview

The Allegro A1366 is a factory-programmable linear Hall-effect current sensor IC engineered for high accuracy and resolution. It features proprietary linearly interpolated temperature compensation technology, ensuring virtually flat sensitivity and offset across its operating temperature range. This makes it ideal for demanding current sensing applications in HEV inverters, DC-to-DC converters, and electric power steering (EPS) systems. The device offers a ratiometric voltage output proportional to the applied magnetic field, with factory-programmed sensitivity and quiescent voltage for accuracy under 1% typical over temperature. Its design incorporates a highly sensitive Hall element, a low-noise BiCMOS interface, and advanced dynamic offset cancellation, achieving an industry-leading sensing resolution at a 120 kHz bandwidth. Built-in broken ground wire detection enhances reliability in automotive environments.
