AH1806
Description
The AH1806 is a high-sensitivity, micro-power Omnipolar Hall effect switch IC, designed for portable and battery powered consumer to home appliance and industrial applications such as smart-meter magnetic tamper detection. Based on two sensitive Hall effect plates and a copper stabilized architecture the AH1806 provides a reliable solution over the whole operating range. To support portable and battery powered equipment, the design has been optimized to operate over the supply range of 2.5V to 5.5V and consumes only 24µW with a supply of 3V.

The single-open-drain output can be switched on with either a North or South pole of sufficient field strength. When the magnetic flux density (B) perpendicular to the package is larger than operate point (Bop) the output is switched on (pulled low). The output is turned off when B bees lower than the release point (Brp). The output will remain off when there is no magnetic field.
