AH3360
HIGH SENSITIVITY MICROPOWER
UNIPOLAR HALL-EFFECT SWITCH
Description
The AH3360 is a high sensitivity micro power unipolar hall effect
switch IC with internal pull-up and pull-down capability. Designed for
battery powered consumer such as cellular phones and portable PCs
to home appliance and industrial equipment, the average supply
current is only 4.3µA at 1.85V. To support portable equipment, the
AH3360 can operate over the supply range of 1.6V to 3.6V, and uses
a hibernating clocking system to minimize the power consumption. To
minimize PCB space, the AH3360 is available in small and low profile
SOT553, X1-DFN1216-4 and X2-DFN2015-6 packages.
The output is activated with a south pole of sufficient magnetic field
strength. When the magnetic flux density (B) perpendicular to the
package is larger than operate point (BOP), the output will be turned
on (pulled low) and held until B is lower than release point (BRP). The
output will remain off when there is no magnetic field.
Features

Notes: 6. Stresses greater than the 'Absolute Maximum Ratings' specified above can 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 can be
affected by exposure to absolute maximum rating conditions for extended periods of time.
7. The absolute maximum VDD of 6V 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.
