Product Description

Product Overview

The BU52072GWZ is an omnipolar detection Hall IC with separate outputs for both South and North pole detection. It features micro-power operation using an intermittent method, an ultra-compact package, and polarity judgment with distinct outputs for each pole (OUT1 for S-pole, OUT2 for N-pole). This Hall IC is ideal for detecting cover open/close in devices like tablets and smartphones, and for determining front/back location or rotational direction of display panels in digital video cameras.
