差動霍爾效應(yīng)集成電路

HAL 300和HAL 320是以CMOS技術(shù)生產(chǎn)的差動開關(guān)。傳感器包括兩個主動偏置補償?shù)臏囟妊a償霍爾片，一個帶有施密特觸發(fā)器的差動放大器，和一個開漏輸出晶體管。差動傳感器感應(yīng)磁場的空間位置變化。差動放大器會放大S1和S2兩塊霍爾片的霍爾電壓。差動信號和施密特觸發(fā)器中預(yù)設(shè)的開關(guān)值進行比較。相應(yīng)地，輸出晶體管進行開關(guān)動作。在HAL300打標(biāo)面封裝前旋轉(zhuǎn)的多極磁環(huán)可以產(chǎn)生差動信號，或者在HAL320的封裝背面在兩個霍爾片產(chǎn)生反偏壓。主動偏置補償使得磁參數(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，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;
