AH1893
HIGH SENSITIVITY MICROPOWER
OMNIPOLAR HALL-EFFECT SWITCH
Description
The AH1893 is a high sensitivity micropower Omnipolar Hall effect
switch IC with internal pull up and pull down capability. Designed for
portable and battery powered equipment such as cellular phones and
portable PCs to home appliances and industrial applications, the
average supply current is only 4.3µA at 1.85V. To support potable
equipment the AH1893 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 AH1893 is available in
small low profile X1-DFN1216-4 and SOT553 packages.
The 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) and held until B is lower than
release point (Brp).

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.
