Description
The US3881 is a bipolar Hall effect sensor IC fabri-
cated 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 commutation applications in 5V and
12V brushless DC motors.
The output transistor will be latched on (B
OP
) in the
presence of a sufficiently strong South pole mag-
netic field facing the marked side of the package.
Similarly, the output will be latched off (B
RP
) in the
presence of a North field.
The SOT-23 device is reversed from the UA pack-
age. The SOT-23 output transistor will be latched
on in the presence of a sufficiently strong North
pole magnetic field subjected to the marked face.
