AH1809
LOW SENSITIVITY MICROPOWER
OMNIPLOAR HALL-EFFECT SWITCH
Description
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.
