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.
