雙極霍爾和全極霍爾目前是常用的霍爾元件，***應(yīng)用于開(kāi)關(guān)，測(cè)速，計(jì)量等應(yīng)用的產(chǎn)品上，但是實(shí)際應(yīng)用中很多人誤將雙極當(dāng)成全極，或者全極當(dāng)成雙極，造成在搭建霍爾電路或者設(shè)計(jì)電路時(shí)的困擾?，F(xiàn)在我們就來(lái)詳細(xì)講下如何正確區(qū)分雙極霍爾元件和全極霍爾元件。1.雙極霍爾元件雙極霍爾一般都要指定一個(gè)磁極，同時(shí)需要兩個(gè)磁極分別控制高低電平，利用磁場(chǎng)NS極交替來(lái)輸出信號(hào)。如S極靠近時(shí)輸出低電平，N極靠近時(shí)輸出高電平。雙極霍爾典型應(yīng)用就是測(cè)速或者計(jì)數(shù)。如果磁場(chǎng)被移除，則是隨機(jī)輸出，有可能是打開(kāi)，也有可能是關(guān)閉。雙極性霍爾元件特點(diǎn)：穩(wěn)定性好，高靈敏度，寬電壓，一致性好，壽命長(zhǎng)。2.全極霍爾元件全極性霍爾又叫無(wú)極性霍爾，其感應(yīng)方式為：全極霍爾不分南（S）北極(N)檢測(cè)磁場(chǎng)，磁鐵接近時(shí)輸出低電平，遠(yuǎn)離時(shí)輸出高電平，全極霍爾的感應(yīng)方式與單極霍爾的感應(yīng)方式相似，區(qū)別在于，單極性霍爾開(kāi)關(guān)會(huì)指定磁極，而全極性霍爾開(kāi)關(guān)不會(huì)指定磁極，任何磁極靠近輸出低電平信號(hào)，離開(kāi)輸出高電平信號(hào)。全極霍爾元件特點(diǎn)：低電壓，低功耗。中國(guó)霍爾質(zhì)量供應(yīng)商,選霍爾,找華芯!華芯十六年專(zhuān)業(yè)做霍爾,精度高,一致性好,靈敏度高,可替代各大進(jìn)口品牌。</p><div
