FOR AUTOMOTIVE 150°C OPERATION HIGH-WITHSTAND VOLTAGE
HIGH-SPEED BIPOLAR HALL EFFECT LATCH
Rev.1.1_00
© Seiko Instruments Inc., 2015
The S-57P1 S Series, developed by CMOS technology, is a high-accuracy Hall IC that operates with high temperature and
high-withstand voltage.
The output voltage changes when the S-57P1 S Series detects the intensity level of magnetic flux density and a polarity
change. Using the S-57P1 S Series with a magnet makes it possible to detect the rotation status in various devices.
The S-57P1 S Series includes a reverse voltage protection circuit and an output current limit circuit.
High-density mounting is possible by using the small SOT-23-3S package.
Due to its high-accuracy magnetic characteristics, the S-57P1 S Series enables the user to reduce the operational variation
in the system.
Caution
This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the

*1. BOP: Operation point
BOP is the value of magnetic flux density when the output voltage (VOUT) changes after the magnetic flux density
applied to the S-57P1 S Series by the magnet (S pole) is increased (by moving the magnet closer).
VOUT retains the status until a magnetic flux density of the N pole higher than BRP is applied.
*2. BRP: Release point
BRP is the value of magnetic flux density when the output voltage (VOUT) changes after the magnetic flux density
applied to the S-57P1 S Series by the magnet (N pole) is increased (by moving the magnet closer).
VOUT retains the status until a magnetic flux density of the S pole higher than BOP is applied.
*3. BHYS: Hysteresis width
BHYS is the difference of magnetic flux density between BOP and BRP.
Remark
6
The unit of magnetic density mT can be converted by using the formula 1 mT = 10 Gauss.

Basic operation
The S-57P1 S Series changes the output voltage (VOUT) according to the level of the magnetic flux density (N pole or S
pole) and a polarity change applied by a magnet.
Definition of the magnetic field is performed every operating cycle indicated in " Electrical Characteristics".
3. 1
Product with VOUT = "L" at S pole detection
When the magnetic flux density of the S pole perpendicular to the marking surface exceeds the operation point
(BOP) after the S pole of a magnet is moved closer to the marking surface of the S-57P1 S Series, VOUT changes
from "H" to "L". When the N pole of a magnet is moved closer to the marking surface of the S-57P1 S Series and
the magnetic flux density of the N pole is higher than the release point (BRP), VOUT changes from "L" to "H". In case
of BRP < B < BOP, VOUT retains the status. Figure 10 shows the relationship between the magnetic flux density and
VOUT.

the N pole is higher than BRP, VOUT changes from "H" to "L". In case of BRP < B < BOP, VOUT retains the status.

 Precautions
• If the impedance of the power supply is high, the IC may malfunction due to a supply voltage drop caused by feedthrough 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. 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.
• 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 package power dissipation.
• 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.
