霍爾傳感器的分類：霍爾傳感器分為線性型霍爾傳感器和開關(guān)型霍爾傳感器兩種。（1）線性型霍爾傳感器由霍爾元件、線性放大器和射極跟隨器組成，它輸出模擬量。（2）開關(guān)型霍爾傳感器由穩(wěn)壓器、霍爾元件、差分放大器，斯密特觸發(fā)器和輸出級組成，它輸出數(shù)字量。線性型霍爾傳感器的特性：輸出電壓與外加磁場強度呈線性關(guān)系，在B1～B2的磁感應強度范圍內(nèi)有較好的線性度，磁感應強度超出此范圍時則呈現(xiàn)飽和狀態(tài)。集成霍爾傳感器分為線性型、開關(guān)型和鎖鍵型等多種,其主要元件均是利用霍爾效應原理制成的.所謂霍爾效應,指的是這樣一種物理現(xiàn)象:如果把通有電流I的導體放在垂直于它的磁場中,則在導體的兩側(cè)P1、P2會產(chǎn)生一電勢差UH,它與電流I及磁感應強度B成正比,與導體厚度d成反比,即:UH=K(IB/d),式中K為霍爾系數(shù).霍爾系數(shù)越大,表明霍爾效應越明顯。南京霍爾傳感器代理商價格線性霍爾傳感器是一種模擬信號輸出的磁傳感器，輸出電壓隨輸入的磁力密度線性變化。</p><div

style="text-indent:25px">在使用霍爾傳感器的電路板布局中，要注意以下因素：散熱：盡量增大一次側(cè)電流導線的覆銅面積，可以提高霍爾電流傳感器的散熱能力，從而增加傳感器的比較大平均電流耐受能力。另外，還可以使用更厚銅箔的PCB，或者在初級走線上放置一些散熱過孔，或者把霍爾電流傳感器和PCB走線放置在風道內(nèi)，都可以改善霍爾電流傳感器的平均電流耐受能力。一次側(cè)電流磁場：布局時，應盡量避免大電流的走線靠近霍爾電流傳感器。隔離要求：從系統(tǒng)整體考慮爬電距離和電氣間隙，當霍爾電流傳感器無法滿足所需的PCB爬電距離時，可以在電路板上挖槽以達到系統(tǒng)級的隔離要求。作為一種流行的磁傳感器技術(shù)，霍爾傳感器的原理是在向?qū)w施加垂直磁場時，在載流導體中會產(chǎn)生差分電壓。</p><div
