Product Overview

The SL172x Series is a high-performance, low-power Hall 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. This sensor detects a single N-pole magnetic field, providing a low output level when the N-pole magnetic induction exceeds the operating point (BOP) and a high output level when it drops below the release point (BRP). Featuring built-in temperature compensation and clock logic circuits, it ensures stable operating points and switching frequencies. The sensor operates within a wide voltage range of 1.8V to 5.5V and is available in SOT-23-3L and TO-92S packages. Its typical applications include switch detection in laptops and tablets, TWS earbuds, mobile phones, electronic locks, valve position detection, and utility meters.
