SL170x Series Hall Effect Switch Sensor
The SL170x series is a low-power Hall effect switch sensor designed for space-constrained and battery-sensitive systems. It offers versatile magnetic threshold options, switching frequencies, and package types to suit various applications. The sensor detects both South (S) and North (N) poles of a magnetic field. When the magnetic field strength exceeds the operating point (BOP), the output switches to a low level and remains there until the field strength drops below the release point (BRP), at which point the output returns to a high level. Featuring integrated temperature compensation and clock logic circuits, the SL170x ensures stable operating points and switching frequencies. It operates across a wide supply voltage range and provides omnipolar magnetic response with minimal current consumption.
