US5881 CMOS Multi-Purpose Switch • • • • • • • • • Features and Benefits Chopper stabilized amplifier stage New miniature package / thin, high reliability package Operation down to 3.5V CMOS for optimum stability, quality and cost Applications Solid state switch Limit switch Current limit Interrupter Current sensing Ordering Information Part No. US5881 US5881 Temperature Suffix Package Temperature Range E SO or UA -40oC to 85oC Extended L SO or UA -40oC to 150oC Automotive *Contact factory or sales representative for legacy temperature options Functional Diagram Description The US5881 is a unipolar Hall effect sensor IC fabricated from mixed signal CMOS technology. It incorporates advanced chopper stabilization techniques to provide accurate and stable magnetic switch points. There are many applications for this sensor in addition to those listed above. The design, specifications and performance have been optimized for applications of solid state switches. The output transistor will b switched on (BOP) in e the presence of a sufficiently strong South pole magnetic field facing the marked side of the package. 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 transistor will be switched on (BOP) in the presence of a sufficiently strong North pole magnetic field subjected to the marked face.
