AH1902  
HIGH SENSITIVITY MICROPOWER  
OMNIPLOAR HALL-EFFECT SWITCH  
Description  
Pin Assignments  
The AH1902 is a high sensitivity micropower Omnipolar Hall effect  
switch IC with internal pull up and pull down capability. Designed for  
portable and battery powered consumer equipment such as cellular  
phones and portable PCs to office equipment, home appliances and  
industrial applications, the average supply current is only 4.3uA at  
1.8V. To support potable equipment the AH1902 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  
AH1902 is available in small low profile X1-DFN1216-4 and X2-  
DFN2015-6 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).

Small Low Profile X1-DFN1216-4 and X2-DFN2015-6 Packages  
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  
Halogen and Antimony Free. “Green” Device (Note 3)  
Notes:  
1. EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. All applicable RoHS exemptions applied.  
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 and should be placed as close to  
the supply pin as possible.
