AKM Releases Ultra-Small Tri-Axis Magnetic Smart Switch with 1/5 of the Packaging Area



Asahi Kasei Microdevices Corporation (AKM) has released the AK09970D, a device with a much smaller overall footprint than the conventional tri-axis magnetic smart switch sensor, the AK09970N. Mobile devices such as smartphones and various wearable devices can be equipped with this sensor that require low power consumption and a high degree of freedom in placement.

For more information on how to use the tri-axis magnetic smart switch sensors, including the AK09970D, you can find an informational video on the “S-cube” special site.



Reduction of Package Area to 1/5 of Conventional Product

By adopting a 1.35mm, 6-pin WL-CSP package, the area has been reduced to an ultra-small size compared to the conventional 3.0mm, 16-pin QFN package.

Power Saving Function (Low Power Consumption, Magnetic Event Notification)

The AK09970D achieves a low average current consumption of 1.0uA @1Hz. It also has the ability to notify the system when a magnetic field has exceeded a set threshold through an internal register or through an external output pin. This could allow a system to enter a sleep mode until a magnetic interrupt event occurs.
