Description  
The US5781 is a unipolar Hall effect sensor IC fab-  
ricated from mixed signal CMOS technology. It in-  
corporates advanced chopper stabilization tech-  
niques to provide accurate and stable magnetic  
switch points. There are many applications for this  
sensor in addition to those listed above. The de-  
sign, specifications and performance have been  
optimized for applications of solid state switches.

The output transistor will be switched on (BOP) in  
the presence of a sufficiently strong South pole  
magnetic field facing the marked side of the pack-  
age. Similarly, the output will be switched off (BRP)  
in the presence of a weaker South field and remain  
off with “0” field. The SOT-23 device is reversed  
from the UA package. The SOT-23 output transis-  
tor will be switched on (BOP) in the presence of a  
sufficiently strong North pole magnetic field sub-  
jected to the marked face.

Note: This is a static-sensitive device; please observe ESD precau-  
tions. Reverse VDD protection is not included. For reverse voltage  
protection, a 100  
Wresistor in series with VDD is recommended.
