Product Overview
The Allegro A1363 is a low-noise, high-precision, programmable linear Hall-effect current sensor IC designed for high accuracy and resolution without compromising bandwidth. 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 90 kHz bandwidth, it is ideal for HEV inverter, DC-to-DC converter, and electric power steering (EPS) applications. This ratiometric sensor IC provides a voltage output proportional to the applied magnetic field and allows customer configuration of sensitivity and quiescent output voltage via programming on the VCC and output pins. It incorporates a highly sensitive Hall element with a BiCMOS interface IC, low noise amplifier, clamped output stage, and dynamic offset cancellation technique. The device offers features like broken ground wire detection and user-selectable output voltage clamps for high reliability in automotive applications, with parameters specified across the full automotive temperature range of 40C to 150C.
