Our patented, best-in-class GMR technology provides low jitter and high air gap over the widest installation tolerance—it also offers high accuracy for extremely precise wheel speed and position measurement, ideal for advanced braking and autonomous vehicle applications. Allegro's advanced, dynamic algorithms compensate for anomalies in driving behavior, guaranteeing steady state output behavior in the presence of system variation.
Allegro also offers a full line of Hall-based wheel speed devices for applications with both ferrous and ring magnet targets.
Plus, safety is one of our top priorities. Allegro’s latest portfolio offerings are designed to ISO 26262 specifications with integrated diagnostics and a certified safety design process.
The A19250 is a giant magnetoresistance (GMR) integrated circuit (IC) that provides a user-friendly two-wire solution for applications where speed information is required.
