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.
Application Examples
Hall Latch – High Sensitivity
Automotive, Consumer and Industrial
Solid-state switch
Brushless DC motor commutation
Speed detection
Linear position detection
Angular position detection
Proximity detection
