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

... Detailed General Description Based on mixed signal CMOS technology, Melexis US3881 is a Hall-effect device with high magnetic sensitivity. This multi-purpose latch suits most of the application requirements. The chopper-stabilized amplifier uses switched capacitor techniques to suppress the offset generally observed with Hall sensors and amplifiers. The CMOS technology makes this advanced technique possible and contributes to smaller chip size and lower current consumption than bipolar technology ...
