AH3360
HIGH SENSITIVITY MICROPOWER
UNIPOLAR HALL-EFFECT SWITCH
Description
The AH3360 is a high sensitivity micropower 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 4.3uA 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 low profile
SOT553, X1-DFN1216-4 and X2-DFN2015-6 and packages.
Pin Assignments
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.

Applications
Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"
and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
Typical Applications Circuit
Note:
4. CIN is for power stabilization and to strengthen the noise immunity, the recommended capacitance is 100nF typical.

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 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.
