HIGH-SPEED BIPOLAR HALL EFFECT LATCH
© SII Semiconductor Corporation, 2013-2015
Rev.1.5_01
The S-57K1 A 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-57K1 A Series detects the intensity level of magnetic flux density and a polarity
change. Using the S-57K1 A Series with a magnet makes it possible to detect the rotation status in various devices.
The S-57K1 A Series includes a reverse voltage protection circuit and an output current limit circuit.
High-density mounting is possible by using the small SOT-23-3 package.
Due to its high-accuracy magnetic characteristics, the S-57K1 A Series can make operation's dispersion in the system
combined with magnet smaller.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the
purpose, contact to SII Semiconductor Corporation is indispensable.

Precautions
• If the impedance of the power supply is high, the IC may malfunction due to a supply voltage drop caused by feed-
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. 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 Semiconductor Corporation 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.
