AH1809

LOW SENSITIVITY MICROPOWER

OMNIPLOAR HALL-EFFECT SWITCH

Description

Pin Assignments

The AH1809 is a low sensitivity micropower Omnipolar Hall Effect

switch IC. It is designed for battery powered consumer products,

home appliances, and industrial equipment such smart e-meters.

Based on two Hall Effect plates and a chopper stabilized architecture

the AH1809 provides a reliable solution over the whole operating

range. To support battery and low power applications 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 strength. When the magnetic flux density

perpendicular to the package (B) 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.

The AH1809 is available in SC59, SOT553 and SIP-3L.

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_DDof 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.
