MAGNETIC POSITION SENSORS
Hall Position Sensor for Linear and Off-Axis Applications
The AS5403 is a Hall sensor which detect linear or rotary off-axis movement of a 2-pole magnet.
Using two Hall cells allows absolute (single pixel) as well as differential (double pixel) magnetic field measurement. The differential measurement makes the AS5403 ideal for use in rough automotive position sensing applications that include not only dust, dirt or moisture but also unwanted magnetic stray fields.
The IC has signal conditioning features, including compensation of temperature effects as well as linearization. The build in diagnostic functions makes the AS5403 suitable for safety critical applications.
