HIGH-SPEED / MIDDLE-SPEED LOW CURRENT CONSUMPTION
BOTH POLES / UNIPOLAR DETECTION TYPE HALL IC
© Seiko Instruments Inc., 2011-2012 Rev.2.3_00
Seiko Instruments Inc. 1
The S-5715 Series, developed by CMOS technology, is a high-accuracy Hall IC that operates with high-speed / middle-
speed detection and low current consumption.
The output voltage changes when the S-5715 Series detects the intensity level of flux density. Using the S-5715 Series with
a magnet makes it possible to detect the open / close and rotation state in various devices.
High-density mounting is possible by using the small SOT-23-3 or the super-small SNT-4A packages.
Due to its high-accuracy magnetic characteristics, the S-5715 Series can make operation’s dispersion in the system
combined with magnet smaller.
Caution This product is intended to use in general electronic devices such as consumer electronics, office
equipment, and communications devices. Before using the product in medical equipment or
automobile equipment including car audio, keyless entry and engine control unit, contact to SII is
indispensable.

OPN, BOPS: Operation points
BOPN and BOPS are the values of magnetic flux density when the output voltage (VOUT) is inverted after the magnetic flux
density applied to the S-5715 Series by the magnet (N pole or S pole) is increased (the magnet is moved closer).
Even when the magnetic flux density exceeds BOPN or BOPS, VOUT retains the status.
*2. B
RPN, BRPS: Release points
BRPN and BRPS are the values of magnetic flux density when the output voltage (VOUT) is inverted after the magnetic flux
density applied to the S-5715 Series 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. B
HYSN, BHYSS: Hysteresis widths
BHYSN and BHYSS are the difference 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.

Operation
1. Direction of applied magnetic flux
The S-5715 Series detects the flux density which is vertical to the marking surface.
In product with both poles detection, the output voltage (VOUT) is inverted when the S pole or N pole is moved closer to
the marking surface.
In product with S pole detection, the output voltage (VOUT) is inverted when the S pole is moved closer to the marking
surface.
In product with N pole detection, the output voltage (VOUT) is inverted when the N pole is moved closer to the marking
surface.
Figure 12 and Figure 13 show the direction in which magnetic flux is being applied.

3. Basic operation
The S-5715 Series changes the output voltage level (VOUT) 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 magnetism detection logic is active "L".
3. 1 Product with both poles detection
When the magnetic flux density vertical to the marking surface exceeds BOPN or BOPS after the S pole or N pole of a
magnet is moved closer to the marking surface of the S-5715 Series, VOUT changes from "H" to "L". When the
S pole or N pole of a magnet is moved further away from the marking surface of the S-5715 Series and the
magnetic flux density is lower than BRPN or BRPS, VOUT changes from "L" to "H".
Figure 16 shows the relationship between the magnetic flux density and VOUT.

moved further away from the marking surface of the S-5715 Series and the magnetic flux density is lower than BRPS,
VOUT changes from "L" to "H".

through current. 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.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• Large stress on this IC may affect on the magnetic characteristics. Avoid large stress which is caused by bend and
distortion during mounting the IC on a board or handle after mounting.
• SII claims no responsibility for any disputes arising out of or in connection with any infringement by products including
this IC of patents owned by a third party.
