Allegro A1363 Programmable Linear Hall-Effect Current Sensor IC

Product Overview

The Allegro A1363 is a high-accuracy, high-resolution programmable linear Hall-effect current sensor IC designed for demanding applications. It features proprietary linearly interpolated temperature compensation technology, programmed at the factory, ensuring virtually flat sensitivity and offset across the full operating temperature range. With a 120 kHz bandwidth and a voltage output proportional to the magnetic field, it is ideal for HEV inverters, DC-to-DC converters, and electric power steering (EPS) systems. The device offers customer-programmable sensitivity and quiescent output voltage for optimized performance, along with advanced features like broken ground wire detection and selectable output voltage clamps for enhanced reliability in automotive environments.
