CMOS High Sensitivity Latch
US2881 CMOS High Sensitivity Latch 3901002881 Rev 5.6 23/July/00 Page 1
Description
The design specifications and performance of the
Melexis US2881 have been optimized for commu-
tation applications in brushless DC motors and
automotive speed sensing.
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 package. The SOT-23 output
transistor will be latched on (B
OP
) in the presence
of a sufficiently strong North pole magnetic field
subjected to the marked face.
