2 General Description
The Melexis US2881 is a bipolar Hall-effect switch
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
suitable for use in automotive 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
Automotive, Consumer and Industrial
Solid-state switch
Brushless DC motor commutation
Speed detection
Linear position detection
Angular position detection
Proximity detection
