Diodes – AH1806/08: High Sensitivity Micropower Omnipolar Hall-Effect Switches

The AH1806 and AH1808 are high sensitivity micropower omnipolar hall-effect switch ICs, specifically designed for portable and battery-powered consumer to home appliances and industrial applications. The high sensitivity hall effect switches have been optimized to operate over the supply range of 2.5V to 5.5V and use a micropower sleep function to give an average supply current of only 8µA.
