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.
