BOPN, BOPS: Operation points BOPN and BOPS are the values of magnetic flux density when the output voltage (VOUT) 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 BOPN or BOPS, VOUT retains the status. *2. BRPN, BRPS: Release points BRPN and BRPS are the values of magnetic flux density when the output voltage (VOUT) 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 BRPN or BRPS, VOUT retains the status. *3. BHYSN, BHYSS: Hysteresis widths BHYSN and BHYSS are the difference between BOPN and BRPN, and BOPS and BRPS, respectively. Remark 6 The unit of magnetic density mT can be converted by using the formula 1 mT = 10 Gauss.

Figure 12 9 FOR AUTOMOTIVE 125C OPERATION HIGH-WITHSTAND VOLTAGE HIGH-SPEED UNIPOLAR DETECTION TYPE HALL EFFECT SWITCH IC Rev.1.7_01 S-57A1 A Series 3. Basic operation This IC changes the output voltage (V OUT ) according to the level of the magnetic flux density (N pole or S pole) applied by a magnet. The following explains the operation when the output logic is active "L". 3. 1 Product with S pole detection When the magnetic flux density of the S pole perpendicular to the marking surface exceeds the operation point (BOPS) after the S pole of a magnet is moved closer to the marking surface of this IC, VOUT changes from "H" to "L". When the S pole of a magnet is moved further away from the marking surface of this IC and the magnetic flux density is lower than the release point (BRPS), VOUT changes from "L" to "H". Figure 13 shows the relationship between the magnetic flux density and VOUT. VOUT BHYSS H L N pole BRPS 0 S pole BOPS Magnetic flux density (B) Figure 13 3. 2 Product with N pole detection When the magnetic flux density of the N pole perpendicular to the marking surface exceeds the operation point (BOPN) after the N pole of a magnet is moved closer to the marking surface of this IC, VOUT changes from "H" to "L". When the N pole of a magnet is moved further away from the marking surface of this IC and the magnetic flux density of the N pole is lower than the release point (BRPN), VOUT changes from "L" to "H". Figure 14 shows the relationship between the magnetic flux density and VOUT.

Take care with the pattern wiring to ensure that the impedance of the power supply is low. Note that the IC may malfunction if the power supply voltage rapidly changes. When the IC is used under the environment where the power supply voltage rapidly changes, it is recommended to judge the output voltage of the IC by reading it multiple times. Note that the output voltage may rarely change if the magnetic flux density between the operation point and the release point is applied to this IC continuously for a long time. Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. Although this IC has a built-in output current limit circuit, it may suffer physical damage such as product deterioration under the environment where the absolute maximum ratings are exceeded. Although this IC has a built-in reverse voltage protection circuit, it may suffer physical damage such as product deterioration under the environment where the absolute maximum ratings are exceeded. The application conditions for the power supply voltage, the pull-up voltage, and the pull-up resistor should not exceed the power dissipation. Large stress on this IC may affect on the magnetic characteristics. Avoid large stress which is caused by the handling during or after mounting the IC on a board.
