Description

The EM1781 is an ultra-compact bipolar detection switch type Hall IC that integrates a Hall element and a waveform shaping IC.
The EM1781 has low power consumption due to intermittent drive, which can reduce current consumption during operation.

Key Features

  • Both pole sensing operation of magnetic field.
    Since it is bipolar detection (omnipolar), it can detect both S and N magnetic fields (know that it is approaching).
  • Intermittent drive operation.
    Because of the intermittent drive operation, current consumption during operation can be reduced.

Applications

  •                                 Rotation detection, position detection, open / close detection, current detection, direction detection, etc.
