*1. B_OP: Operation point
B_OP is the value of magnetic flux density when the output voltage (V_OUT) changes after the magnetic flux density
applied to this IC by the magnet (S pole) is increased (by moving the magnet closer).
V_OUT retains the status until a magnetic flux density of the N pole higher than B_RP is applied.
*2. B_RP: Release point
B_RP is the value of magnetic flux density when the output voltage (V_OUT) changes after the magnetic flux density
applied to this IC by the magnet (N pole) is increased (by moving the magnet closer).
V_OUT retains the status until a magnetic flux density of the S pole higher than B_OP is applied.
*3. B_HYS: Hysteresis width
B_HYS is the difference of magnetic flux density between B_OP and B_RP.
Remark
The unit of magnetic density mT can be converted by using the formula 1 mT = 10 Gauss.
