Low Voltage & Very High Sensitivity
2 General Description
The Melexis US4881 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.
The low operating voltage and extended choice of
temperature ranges make it suitable for use in
automotive, industrial and consumer low voltage
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, Industrial and Consumer
Solid-state switch
Brushless DC motor commutation
Speed detection
Linear position detection
Angular position detection
Proximity detection
