HAL300UA-K

差動(dòng)霍爾效應(yīng)集成電路

HAL 300和HAL 320是以CMOS技術(shù)生產(chǎn)的差動(dòng)開關(guān)。傳感器包括兩個(gè)主動(dòng)偏置補(bǔ)償?shù)臏囟妊a(bǔ)償霍爾片，一個(gè)帶有施密特觸發(fā)器的差動(dòng)放大器，和一個(gè)開漏輸出晶體管。差動(dòng)傳感器感應(yīng)磁場(chǎng)的空間位置變化。差動(dòng)放大器會(huì)放大S1和S2兩塊霍爾片的霍爾電壓。差動(dòng)信號(hào)和施密特觸發(fā)器中預(yù)設(shè)的開關(guān)值進(jìn)行比較。相應(yīng)地，輸出晶體管進(jìn)行開關(guān)動(dòng)作。在HAL300打標(biāo)面封裝前旋轉(zhuǎn)的多極磁環(huán)可以產(chǎn)生差動(dòng)信號(hào)，或者在HAL320的封裝背面在兩個(gè)霍爾片產(chǎn)生反偏壓。主動(dòng)偏置補(bǔ)償使得磁參數(shù)在全電壓和全溫度下都是持續(xù)的。該傳感器系為汽車和工業(yè)應(yīng)用設(shè)計(jì)，工作電壓從4.5伏到24伏，溫度范圍從–40 °C up to 170 °C。有SM; ·Distance between Hall plates: 2.05?mm\n·Operates from 4.5 V to 24 V supply voltage\n·Switching offset compensation at 62 kHz\n·Overvoltage protection\n·Reverse-voltage protection at VDD-pin\n·Short-circuit protected open-drain output by thermal shutdown\n·Operates with magnetic fields from DC to 10;
