2 General Description
The Melexis US3881 is
a
Hall-effect la
echnology
tch
designed in mixed signal CMOS
t
.
The device integrates a voltage regulator, Hall
sensor with dynamic offset cancellation sys em
Schmitt trigger and an open-drain output driver, all
in a single package
t
,
.
The low operating voltage and extended choice o
temperature range make it suitable for use in
automotive, industrial and consumer low vol age
applica ions
f
t
t
.
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
hole mount.
Both 3-lead packages are RoHS compliant.
