*1. B_OPN, B_OPS: Operation points
B_OPN and B_OPS are the values 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 or S pole) is increased (by moving the magnet closer).
Even when the magnetic flux density exceeds B_OPN or B_OPS, V_OUT retains the status.
*2. B_RPN, B_RPS: Release points
B_RPN and B_RPS are the values 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 or S pole) is decreased (the magnet is moved further away).
Even when the magnetic flux density falls below B_RPN or B_RPS, V_OUT retains the status.
*3. B_HYSN, B_HYSS: Hysteresis widths
B_HYSN and B_HYSS are the difference between B_OPN and B_RPN, and B_OPS and B_RPS, respectively.
Remark The unit of magnetic density mT can be converted by using the formula 1 mT = 10 Gauss.
