Product Overview

The Allegro A1363 is a programmable linear Hall-effect current sensor IC engineered for high accuracy and resolution without sacrificing bandwidth. It features proprietary linearly interpolated temperature compensation technology, programmed at the factory, ensuring virtually flat sensitivity and offset across the operating temperature range. With a 120 kHz bandwidth, it is ideal for demanding applications such as HEV inverters, DC-to-DC converters, and electric power steering (EPS). This ratiometric sensor provides a voltage output proportional to the magnetic field and allows user configuration of sensitivity and quiescent output voltage for optimized performance. It incorporates a highly sensitive Hall element, a low-noise BiCMOS interface, and advanced dynamic offset cancellation for industry-leading sensing resolution.
