AH1806

HIGH SENSIVITY MICROPOWER

OMNIPOLAR HALL-EFFECT SWITCH

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 becomes lower than the release point (Brp). The output will remain

off when there is no magnetic field.

Notes:

6. 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 V

DD

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.
