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 (B
OP
), the output will be turned
on (pulled low) and held until B is lower than release point (B
RP
). The
output will remain off when there is no magnetic field.
