AH1822 Overview
AH1822 is prised of two Hall effect plates and an open-drain output driver, mainly designed for battery-operation, hand-held equipment (such as Cellular and Cordless Phone, PDA). The total power consumption in normal operation is typically 24µW with a 3V power source. Either north or south pole of sufficient strength will turn the output on.
