AS1518

Tri-Axial Digital Geomagnetic Sensor

General Description

    The AS1518 is a low-power digital geomagnetic sensor for consumer e-compass applications. A highly sensitive Hall-effect magnetic sensor is directly integrated with the signal conditioning IC in monolithic wafer process. The 4-pin wafer level chip scale package (WLCSP) measures only 0.8×0.8×0.5mm3. This small package size dramatically increases the design flexibility to developers of compact mobile devices.
    AS1518 can work harmoniously with the 3-axis digital accelerometer for directional information. The magnetometer detects the terrestrial magnetism to be compensated by the tilt angle determined from the accelerometer for providing precise navigation heading.
    The device is a RoHs and Green compliant WLCSP-4B package.
