$Fonctionnalités et applications

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.

Features and Benefits:

  • Operating voltage range from 2.2V to 18V
  • Very high magnetic sensitivity
  • CMOS technology
  • Chopper-stabilized amplifier stage
  • Low current consumption
  • Open drain output
  • Thin SOT23 3L and flat TO-92 3L both RoHS Compliant packages
  • SE package North Pole Active
  • UA package South Pole Active


  • Automotive
  • Industrial and Consumer
  • Solid-state switch
  • Brushless DC motor commutation
  • Speed detection
  • Linear position detection
  • Angular position detection
  • Proximity detection
