2 General Descriptioon
The Melexis US5881 is a unipolar Hall-effect
switch designed in mixeed signal CMOS
technology.
The device integrates a volltage regulator, Hall
sensor with dynamic offset ccancellation system,
Schmitt trigger and an open-drain output driver, all
in a single package.
Thanks to its wide operatingg voltage range and
extended choice of temperrature range, it is
suitable for use in automottive and solid state
switch applications.
The device is delivered in aa Thin Small Outline
Transistor (TSOT) for surface mount process and
in a Plastic Single In Line (TOO-92 flat) for through-
hole mount.
Both 3-lead packages are RoHHS compliant.
