Product Overview
The SL1619 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 sensor detects a single S-pole magnetic field, providing a low output when the magnetic field strength exceeds the operating point (Bop) and a high output when it drops below the release point (Brp). With a wide operating voltage range of 1.6V to 5.5V and excellent ESD performance, it is suitable for a variety of applications including laptop/tablet switch detection, TWS earbuds, mobile phones, electronic locks, valve position detection, and non-contact metering.
