2 General Description

The Melexis US3881 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.

The low operating voltage and extended choice of

temperature range make it suitable for use in

automotive, industrial and consumer low voltage

applications.

The devices are 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.
