Product Overview

The BU5277GWZ is an omnipolar detection Hall IC with separate outputs for South and North pole detection. It utilizes an intermittent operation method for micro power consumption, making it ideal for battery-powered devices. This ultra-compact Hall IC enables the detection of cover open/close states in smartphones and tablets, and can be used for detecting the insertion of wireless earphones into their cases, or for front/back side and rotational direction detection in digital cameras and other display panel applications.
