Product Overview

The BU52077GWZ is an omnipolar Hall IC featuring a polarity determination circuit for separate operation of both South and North poles. It is designed for applications requiring detection of cover open/close states in devices like tablets and smartphones, and for determining the front/back location or rotational direction of display panels in digital video cameras. Its key advantage is the ability to detect both polarities with separate, dual outputs, combined with micro-power operation and an ultra-compact package.
