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 (B
OP
) 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 (B
RP
)
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
OP
) 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 V

protection is not included. For reverse voltage
protection, a 100
W
resistor in series with V
DD
is recommended.
