Description

AK09974C is a ultra-small tri-axis magnetic sensor IC based on Hall sensor technology.
It delivers high-resolution 16-bit digital output for magnetic field strength in the X, Y, and Z directions, with wide range and low noise. Advanced features include magnetic switch functionality, arctangent calculation, and I3C-based interrupt support.
Ideal for space-saving position and tilt detection when paired with a small magnet, AK09974C is well-suited for smartwatches, mobile devices, and XR applications.

Key Features

Stable and high-precision sensing achieved by its wide measurement range and low-noise design

Built-in processing functions for simpler, more power-efficient systems

Compact package and wide measurement range enable space-saving, miniaturized designs

Applications

                                Smartphones, Wearables, Gaming, XR devices, etc.
