AH1812
HIGH SENSIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH
Description
The AH1812 is a high sensitivity micropower Omnipolar Hall effect
switch IC with an open drain output. Designed for portable and battery
powered equipment such as cellular phones and portable PCs, the
average supply current is only 4.3µA at 1.85V. To support potable
equipment the AH1812 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 AH1812 is available in
small low profile X1-DFN1216-4 package
The open drain output is activated with either a North or 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). 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.

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)
Note:
4. CIN is for power stabilization and to strengthen the noise immunity, the recommended capacitance is 10nF to 100nF.
RL is the pull-up resistor, the recommended resistance is 10kΩ to 100kΩ.
