Micropower ホール効果スイッチ

AN296238 - In this applicate note, we discuss the use of the APS13568, an integrated circuit that combines an ultra-sensitive, omnipolar, micropower Hall-effect switch with a linear programmable current regulator which can provide up to 150 mA current to drive high brightness LEDs.

Join our webinar for a refresher on magnetic sensing technologies and an exploration of the latest technical innovations aimed at reducing power consumption in these versatile, reliable, and high-performance solid-state sensors.

This application note discusses the fundamental principles that govern micropower switch and latch magnetic sensors.

Let's explore the intricacies of designing a robust and effective window open detection solution for security systems.

AN296192 - This application note will discuss the technical considerations necessary to aid with the replacement of an on/off mechanical switch with a Hall-effect switch.

There are four general categories of Hall-effect IC devices that provide a digital output: unipolar switches, bipolar switches, omnipolar switches, and latches. Latching Hall-effect sensor ICs, often referred to as "latches," are digital output Hall-effect switches that latch output states.

This application note assumes the user is programming an Allegro fully integrated back biased Hall effect switch or that the user has designed an appropriate magnetic circuit to accommodate the programming range of a programmable unipolar Hall effect switch.

This note will show how to use the Allegro™ A1171 in a standard flip or slide phone, as well as techniques for sensing three positions using only one magnet and one Hall device in a multipurpose application.

This application guide will outline the differences between the two sensor types and provide system designers with the tools needed in order to select the appropriate sensor for their system.
