A19360 High-Resolution GMR Wheel Speed and Distance Sensor IC
●The A19360 is a magnetic sensor integrated circuit (IC) that uses giant magnetoresistance (GMR) technology to encode the speed and direction of rotating ring magnets. Innovative algorithms generate additional events per magnetic cycle while staying robust to air gap variation, to provide high-resolution rotational data that can be used for accurate distance measurement. The A19360 is compatible with standard ring magnets used in automotive braking systems, and Allegro programs each IC according to the characteristics of the magnet used.
●The A19360 is available in two resolution options (4 or 8 events per cycle) and two protocol options (Pulse Width or AK Protocol). The 4-event AK Protocol option uses 28 mA speed pulses for every event and operates continuously throughout the full frequency range using standard bit truncation at higher speeds. The 8-event AK Protocol option uses 14 mA speed pulses for high-resolution events and features an automatic crossover to standard-resolution at higher speeds, maximizing the available bandwidth of the two-wire interface.
●The A19360 was developed in accordance with ISO 26262 as a hardware safety element out of context, rated ASIL B(D) (pending assessment) for use in automotive safety-related systems when integrated and used in the manner prescribed in the applicable safety manual and datasheet.
●The A19360 is provided in a 2-pin SIP package (suffix UB) that is lead (Pb) free, with tin lead frame plating. The UB package includes an IC and protection capacitor integrated into a single overmolded package, with an additional molded lead-stabilizing bar for robust shipping and ease of assembly.
