BOPN, BOPS : Operating points The operating points are the values of magnetic flux density when the output voltage (VOUT) is inverted after the magnetic flux density applied to the S-5713A Series by the magnet (N or S pole) is increased (the magnet is moved closer). Even when the magnetic flux density exceeds BOPN or BOPS, VOUT retains the status. BRPN, BRPS : Release points The release points are the values of magnetic flux density when the output voltage (VOUT) is inverted after the magnetic flux density applied to the S-5713A Series by the magnet (N or S pole) is decreased (the magnet is moved further away). Even when the magnetic flux density is lowered than BRPN or BRPS, VOUT retains the status. BHYSN, BHYSS : Hysteresis widths BHYSN and BHYSS are the differences between BOPN and BRPN, and BOPS and BRPS, respectively. Remark The unit of magnetic density mT can be converted by using the formula 1 mT = 10 Gauss. 6 Seiko Instruments Inc. Rev.2.0_00 Test Circuits 1.

Direction of applied magnetic flux and position of Hall sensor The S-5713A Series detects the flux density which is vertical to the marking surface. Figure 9 shows the direction in which magnetic flux is being applied. N S Marking surface Figure 9 Figure 10 shows the position of Hall sensor. The center of this Hall sensor is located in the area indicated by a circle, which is in the center of a package as described below. The following also shows the distance (typ. value) between the marking surface and the chip surface of a package. Top view 1 Center of Hall sensor (φ0.3 mm or less) 2 3 0.7 mm (typ.) Figure 10 Seiko Instruments Inc. 9 HIGH-SPEED UNIPOLAR DETECTION TYPE HALL IC S-5713A Series Rev.2.0_00 2. Basic operation The S-5713A Series changes the output voltage (VOUT) according to the level of the magnetic flux density (N or S pole) applied by a magnet. The following explains the operation when the magnetism detection logic is active “L”. (1) Products with detection of S pole When the magnetic flux density vertical to the marking surface exceeds BOPS after the S pole of a magnet is moved closer to the marking surface of the S-5713A Series, VOUT changes from “H” to “L”. When the S pole of a magnet is moved further away from the marking surface of the S-5713A Series and the magnetic flux density is lower than BRPS, VOUT changes from “L” to “H”. (2) Products with detection of N pole When the magnetic flux density vertical to the marking surface exceeds BOPN after the N pole of a magnet is moved closer to the marking surface of the S-5713A Series, VOUT changes from “H” to “L”. When the N pole of a magnet is moved further away from the marking surface of the S-5713A Series and the magnetic flux density is lower than BRPN, VOUT changes from “L” to “H”. Figures 11 to 12 show the relationship between the magnetic flux density and VOUT.
