General Description

The Melexis US2881 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.

Thanks to its wide operating voltage range and extended choice of temperature range, it is suitable for use in automotive and consumer 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 throughhole
mount.

Both 3-lead packages are RoHS compliant.

Features and Benefits

• Wide operating voltage range from 3.5V to 24V
• 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

Application Examples

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