1 Functional Diagram
2 General Description
The Melexis US5781 is a unipolar 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 solid state
switch 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.
