Product Overview

The A19360 is a high-resolution GMR wheel speed and distance sensor IC utilizing giant magnetoresistance (GMR) technology to encode rotational data from ring magnets. It offers enhanced ADAS accuracy, particularly for automated parking, with GMR technology providing high magnetic sensitivity for large air gaps and low-jitter switching. The SolidSpeed Digital Architecture ensures robust, adaptive performance for high output accuracy and full pitch vibration immunity. This integrated solution combines the IC and a protection capacitor in a single overmolded package and is developed in accordance with ISO 26262 ASIL B(D) with integrated diagnostics and a certified safety design process (pending assessment).
