Product Description
Product Overview
The BU52271NUZ is an omnipolar detection Hall IC featuring a polarity determination circuit that allows for separate operation of both South and North poles. This enables the detection of cover open/close states in devices like tablets and smartphones, as well as front/back side or rotational direction in digital video cameras and other display panel applications. It operates with micro-power consumption using an intermittent operation method and is available in an ultra-compact package.
