Product Overview

The AH1389 is a miniature micropower Hall effect switch IC with dual outputs, designed for portable, battery-powered consumer equipment, home appliances, and industrial applications. It operates from a supply voltage of 1.6V to 3.6V and features a sleep function for low average supply current. The AH1389 offers an 8kV ESD rating and is packaged in a small X2-DFN1410-4 package. A North pole activates Output1, while a South pole activates Output2, enabling independent pole detection for design flexibility.
