AH1903  
HIGH SENSITIVITY MICROPOWER  
UNIPOLAR/OMNIPOLAR SELECTABLE HALL-EFFECT SWITCH  
Description  
Pin Assignments  
The AH1903 is a high sensitivity micropower Omnipolar or Unipolar  
selectable Hall effect switch IC with internal pull up and pull down  
capability. Designed for 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 4.3µA at 1.8V. To support portable equipment the AH1903 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 AH1903 is available in  
X1-DFN1216-4 package.  
a small low profile  
The user can change the Hall switch function between Unipolar and  
Omnipolar operation via the Select (SEL) pin. If the SEL pin is open  
circuit or pulled high the AH1903 operates in Unipolar switch mode  
detecting magnetic field direction with a South pole to the part mark  
side of the package. If the SEL pin is pulled low the AH1903 functions  
as a Omnipolar switch detecting either a North or South pole. The  
output is activated with a 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 Package  
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  
Halogen and Antimony Free. “Green” Device (Note 3)  
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.  
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.
