2 General Description

The Melexis US1881 is a Hall-effect latch

designed in mixed signal CMOS technology.

The device integrates a voltage regulator, Hall

sensor with dynamic offset cancellation system,

Schmitt trigger and an open-drain output driver, all

in a single package.

Thanks to its wide operating voltage range and

extended choice of temperature range, it is quite

suitable for use in automotive, industrial and

consumer applications.

The device is delivered in a Thin Small Outline

Transistor (TSOT) for surface mount process and

in a Plastic Single In Line (TO-92 flat) for through-

hole mount.

Both 3-lead packages are RoHS compliant.
