Product Overview
The SL1625 is a low-power Hall effect switch sensor designed for space-constrained and battery-sensitive systems. It offers selectable magnetic field thresholds (BOP), switch operating frequencies, and package options to suit various applications. The device detects a single N-pole magnetic field, providing a low output when the N-pole magnetic induction strength exceeds the BOP threshold and a high output when it drops below the BRP threshold. With built-in temperature compensation and clock logic circuits, it ensures stable operating points and switching frequencies. The SL1625 operates within a wide voltage range and features a standard SOT-553 package, making it suitable for applications such as laptop/tablet switch detection, TWS earbuds, mobile phones, electronic locks, valve position sensing, and flow meters.
