Seiko Instruments recently rolled out its new -57A1/K1 series of Hall Effect sensor ICs for automotive applications. The Hall Effect sensor ICs detect magnetic field changes and output a high or low voltage level depending on the field strength and polarity.

The SII Hall Effect sensor series includes two basic types of sensor: Unipolar (S-57A1), which is used to detect open/close conditions like doors, seat belts, CD/DVD players, and shift levers and Bipolar (S-57K1), which is used to detect/measure rotation and direction like EPS motors, power windows, and windshield wipers.

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 operationtCYCLE = 16?s (S-57A1) and 8?s (S-57K1).

The sensor IC is packaged in a small SOT-23-3 ( 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.
