Product Overview
The Allegro A1363 is a high-accuracy, high-resolution programmable linear Hall-effect current sensor IC designed for demanding applications such as HEV inverters, DC-to-DC converters, and electric power steering (EPS). It features proprietary linearly interpolated temperature compensation technology for virtually flat sensitivity and offset across the operating temperature range, achieved through digital compensation without sacrificing analog signal path bandwidth. This ratiometric sensor provides a voltage output proportional to the applied magnetic field, with user-configurable sensitivity and quiescent output voltage for optimized end-application performance. It offers a nominal bandwidth of 90 kHz, low noise, and high precision, making it ideal for automotive applications.
