MICROPOWER, ULTRA-SENSITIVE OMNIPOLAR  
HALL-EFFECT SENSOR SWITCH  
Description  
Pin Assignments  
(Top View)  
The AH1802 is a ultra-sensitivity, micropower 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 AH1802 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 24uW with a supply of 3V.

3. GND  
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.
