AH1809
LOW SENSITIVITY MICROPOWER
OMNIPOLAR HALL-EFFECT SWITCH
Description
Pin Assignments
The AH1809 is a low sensitivity micro power Omnipolar Hall Effect
switch IC designed for battery powered consumer to home appliance
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 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 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.

Notes:
8. When power is initially turned on, the operating VDD must be within its correct operating range (2.5V to 3.6V) to guaranteed the output sampling.
The output state is valid after the second operating cycle (typical 150ms).
