Seiko Instruments (SII) Launches New High-Accuracy Hall Effect Sensor ICs for
TOKYO, June 5, 2013
-- High Performance/High Accuracy Featuring Magnetic Operating Point Accuracy
+/-1.5mT, Specifically Developed for Reliable Position/Rotation Detection in
Demanding Automotive Applications -
TOKYO, June 5, 2013 /PRNewswire/ -- Seiko Instruments Inc. (SII) released the
new S-57A1/K1 series of Hall Effect sensor ICs for automotive applications
requiring high performance, reliability, accuracy and magnetic sensitivity.
Hall Effect sensor ICs detect magnetic field changes and output a high or low
voltage level depending on the field strength and polarity. By combining the
sensors with magnets, designers can create applications that operate based on
detecting open/close conditions, relative position, rotation and direction.
The SII Hall Effect sensor series includes two basic types of sensor: Unipolar
(S-57A1) -- used to detect open/close conditions like doors, seat belts,
CD/DVD players, and shift levers -- and Bipolar (S-57K1) -- used to
detect/measure rotation and direction like EPS motors, power windows, and
In addition to high performance and high accuracy, the S-57A1/K1 series
features a wide operating voltage range (VDD = 3.5 to 26.0 V) and operating
temperature range (-40C to 125C), with high-speed operation -- tCYCLE = 16
microseconds (S-57A1) and 8 microseconds (S-57K1).
The sensor IC packaging is small SOT-23-3 (2.9×2.8×1.3mm) and lead
(Pb)-free/halogen-free, making integration in an automotive environment
extremely effective and environmentally friendly.
SII also provides a magnetic simulation consulting service to assist customers
in system design including magnet selection and relative dimensions/locations.
In addition to automobile applications, the S-57A1/K1 series can also be used
in a wide range of other applications including brushless DC motors, home
appliances, housing equipment and industrial equipment.
SII has a well-established and recognized track record for providing reliable
serial EEPROMs to automotive manufacturers. As a result, SII holds the No.1
market share in this category in Japan. SII Hall ICs have seen widespread
adoption for use in smartphones, tablets and laptops, among other devices. SII
has a proven track record of providing high-performance, high-reliability
devices for demanding environments like automotive applications.
