AH1806 HIGH SENSIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH NEW PRODUCT Description Pin Assignments 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. (Top View) SC59 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 becomes lower than the release point (Brp). The output will remain off when there is no magnetic field.

Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only; functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time. 7. The absolute maximum VDD of 7V is a transient stress rating and is not meant as a functional operating condition. It is not recommended to operate the device at the absolute maximum rated conditions for any period of time. Recommended Operating Conditions (@TA = +25°C, unless otherwise specified.)
