AH180N
MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH
Description
The AH180N is a high sensitivity, micro power Omnipolar Hall Effect
switch IC designed for portable and battery powered equipment such
as cellular phones, PDA’ s and portable PC’ s. Based on two sensitive
Hall Effect plates and a chopper stabilized architecture the AH180N
provides a reliable solution over the whole operating range. To
support portable and battery powered equipment the design has been
optimized to operate over the supply range of 2.5V to 5.5V and
consumes only 24µA with a supply of 3V.
Pin Assignments
The single open drain output can switched on with either a North or
South pole of sufficient strength. When the magnetic flux density (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.
Features
• Omnipolar (North or South pole) Operation

• Contact-Less Switch in Consumer Products
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 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.
