Bipolar latch type Hall effect ICs

Switches on/off when the magnetic fields from the S pole and N pole of the magnet are applied alternately.
This is principally applied in detection of revolution speed.

• When the S pole of the magnet approaches the marked side of the Hall effect IC and the magnetic flux density exceeds Bop, Vout changes from H to L.
• When the N pole of the magnet approaches the marked side of the Hall effect IC and the magnetic flux density exceeds Brp, Vout changes from L to H.

The hall element in the Hall IC is always driven. Operating ambient temperature range is -30 to 115°C.
