The S-57P1 series features a wide operating temperature range of -40 ¢ªC up to 150 ¢ªC, a wide operating voltage range from 2.7V to 26.0V, and high magnetic accuracy of ¡¾1.0mT.
The bipolar latch type hall effect sensor ICs detect magnetic field changes and output a high or low voltage level depending on the field strength and polarity. The combination of sensors and magnets allows designers to create applications that operate based on rotation detection.
The S-57P1 Series has high operating temperature up to 150 ¢ªC and junction temperature up to 170 ¢ªC, which enables the use in applications around an engine. The industry leading magnetic accuracy of ¡¾1.0mT improves design flexibility and contributes to total solution cost reduction through the use of smaller magnets. There are multiple options for magnetic sensitivity including 0.5¡¾1.0mT, 1.5¡¾1.0mT, 2.2¡¾1.0mT, and 3.0¡¾1.0mT. The S-57P1 Series is available in the small SOT-23-3S (2.9¡¿2.8¡¿1.2mm) and AEC-Q100 certification is in process.
SII also provides a No Cost magnetic simulation consulting service to support customer¡¯s system designs including magnet and relative dimension / location recommendations.
In addition to automotive applications, the S-57P1 series can also be used in any application needing high temperature and wide operating voltage.
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.
