Magnetic Sensors - Switches (Solid State)

Hall-effect latchHigh sensitivityOpen drainTSOT-23L3.5 V to 24 VRoHS compliant

US1881ESE-AAA-000-RE is a 3-lead high-sensitivity Hall-effect latch for magnetic switching and position or speed sensing from 3.5 V to 24 V.

Best for

  • Magnetic switching
  • BLDC motor commutation
  • Speed sensing
  • Position and proximity sensing

Avoid if

  • A non-latching unipolar Hall switch is required
  • The system cannot provide a pull-up resistor
  • Only one magnetic polarity is available

Check before use

  • Confirm the 0.5 mT to 9.5 mT operating-point range across the required temperature range.
  • Check package-side polarity behavior for the TSOT-23L SE variant.
  • Keep supply and output voltage/current within datasheet limits.
