A1120EUA-T Hall Effect Switch

The A1120EUA Hall-effect, unipolar switches are extremely temperature-stable and stress-resistant sensor ICs.

Each device includes on a single silicon chip a voltage regulator, Hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short-circuit protected open-drain output to sink up to 25 mA. An on-board regulator permits operation with supply voltages of 3 to 24 V. The advantage of operating down to 3 V is that the device can be used in 3 V applications or with additional external resistance in series with the supply pin for greater protection against high voltage transient events.

A south pole of sufficient strength turns the output on. Removal of the magnetic field turns the output off.


  • Unipolar switchpoints
  • Resistant to physical stress
  • Superior temperature stability
  • Output short-circuit protection
  • Operation from unregulated supply
  • Reverse battery protection
  • Solid-state reliability
  • Small package sizes
