AH1804  
MICROPOWER OMNIPOLAR HALL EFFECT SENSORSWITCH  
Description  
Pin Assignments  
( Top View )  
The AH1804 is a micropower Omnipolar Hall effect switch IC  
with a single output driver with internal pull up and pull down  
capability. Designed for portable and battery powered  
equipment such as cellular phones and portable PCs the  
average supply current is only 12µA at 3.3V. To support  
battery powered equipment the AH1804 can operate over the  
supply range of 2.5V to 3.6V and uses a hibernating clocking  
system to minimize the power consumption.

Output

DFN1216-4  
The output is activated with either a north or south pole of  
sufficient strength. When the magnetic flux density (B) is  
larger than operate point (Bop), the output will be turned on  
(pulled low) and held until B is lower than release point (Brp).
