AH1888  
MICROPOWER, GENERAL-SENSITIVE HALL EFFECT  
SWITCH  
Description  
Pin Assignments  
The AH1888 micro power Omni-polar 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 chopper stabilized architecture  
the AH1888 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 1.65V to 3.3V and consumes only 12.6uW  
with a supply of 1.8V.

The outputs are switched 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. 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. The AH1888-ZG has two outputs, output one  
pulls low when switched on and output two is inverted. The  
AH1888-FJG provides output one and AH1888-FJRG  
provides output two.
