A3213傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）規(guī)格書PDF中文資料

A3213屬于傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）。由Allegro MicroSystems制造生產(chǎn)的A3213磁性傳感器 - 開關(guān)（固態(tài)）該系列產(chǎn)品使用固態(tài)技術(shù)來(lái)檢測(cè)是否存在超過某個(gè)特定幅度和/或標(biāo)示的磁場(chǎng)，并提供指示是否存在此類磁場(chǎng)的雙態(tài)輸出。它們與磁簧開關(guān)以及線性或羅盤型固態(tài)器件不同，前者通過使用移動(dòng)機(jī)械部件來(lái)提供類似的功能，后者提供指示所施加磁場(chǎng)的強(qiáng)度和/或方向的可變輸出。

MICROPOWER, ULTRA-SENSITIVE HALL-EFFECT SWITCHES

The A3213xx and A3214xx integrated circuits are ultra-sensitive, pole independent Hall-effect switches with a latched digital output. They are especially suited for operation in battery-operated, hand-held equipment such as cellular and cordless telephones, pagers, and palmtop computers. A 2.4 volt to 5.5 volt operation and a unique clocking scheme reduce the average operating power requirements – the A3213xx to 825 μW, the A3214xx to 14 μW (typical at 2.75 V)! Except for operating duty cycle and average operating current, the A3213xx and A3214xx are identical.
