*1. BOP: Operation point

BOP is the value of magnetic flux density when the output voltage (VOUT) changes after the magnetic flux density applied

to this IC by the magnet (S pole) is increased (by moving the magnet closer).

VOUT retains the status until a magnetic flux density of the N pole higher than BRP is applied.

*2. BRP: Release point

BRP is the value of magnetic flux density when the output voltage (VOUT) changes after the magnetic flux density applied

to this IC by the magnet (N pole) is increased (by moving the magnet closer).

VOUT retains the status until a magnetic flux density of the S pole higher than BOP is applied.

*3. BHYS: Hysteresis width

BHYS is the difference of magnetic flux density between BOP and BRP.

Remark The unit of magnetic flux density mT can be converted by using the formula 1 mT = 10 Gauss.
