Description
The US5881 is a unipolar Hall effect sensor IC fab-
ricated from mixed signal CMOS technology. It i n -
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 b e switched on (B
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 (B
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 (B
sufficiently strong North pole magnetic field sub-
jected to the marked face.
