Micropower ホール効果スイッチ

こうしたホール効果センサーICを内蔵するバッテリ駆動デバイスの寿命を延長します。こうしたスイッチは、消費電力が低く、オン/オフ スイッチング用途、およびユーティリティ メーターの改ざん検出用途に最適です。消費電流は、作動期間と休止期間の再投入により大きく減少します。

Allegro は、いずれかの極性、および任意の方向の磁界を検出できるユニークな 3D 全極性センサー IC を提供しています。こうした製品は非常に感度が高く、スマート メーター、ATM、ギャンブル / ゲーム機、切符販売機、電子ロックなどの用途で磁界による改ざんの検出に最適です。

Application Note

Latching Switch Hall-Effect IC Basics

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.
