1 Functional Diagram
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.
