AK09973D Ultra-Small Tri-Axis Magnetic Sensor with Digital Output

AKM's AK09973D is a tri-axis magnetic sensor IC that utilizes Hall sensor technology. The AK09973D is equipped with a wide-range magnetic sensor that detects a large magnetic field, a sensor driver, a signal amplifier, a calculation logic, and others. It outputs the magnitude of the magnetic field in each of the X-axis, Y-axis, and Z-axis as a digital value. It has a switch function to detect magnetic events according to the threshold setting and notify the outside.

The AK09973D is suitable for use in combination with magnets to detect the relative distance and orientation of the two. It is ideal for detecting the shape of foldable/rollable screen-type smartphones and for ultra-low consumption security applications that utilize the switch function.
