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 range 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.
