Product Overview
The AK09973D is a high-sensitivity 3D magnetic smart switch sensor IC, leveraging advanced Hall sensor technology. It offers a wide measurement range and independently detects magnetic fields along the X, Y, and Z axes. Its ultra-small package, thin profile, and extremely low power consumption make it ideal for integration into smartphones and wearable devices. The sensor provides 16-bit data output for each axis, features a built-in A/D converter, and supports various operational modes including power-down, single measurement, continuous measurement, and self-test. It also includes a programmable 3-axis switch function and an output pin for event notification.
