描述 Description

HAL 7xy是配有S1、S2兩個(gè)獨(dú)立CMOS技術(shù)霍爾片的單體霍爾效應(yīng)傳感器，有兩個(gè)開漏輸出。HAL730具有計(jì)數(shù)和方向輸出。計(jì)數(shù)輸出根據(jù)磁場(chǎng)接近霍爾片S1的情況作霍爾感應(yīng)開關(guān)活動(dòng)。方向輸出指明磁介質(zhì)線性或者旋轉(zhuǎn)運(yùn)動(dòng)的方向。配合活動(dòng)的對(duì)象交替輸出磁場(chǎng)N或S極，產(chǎn)品就能產(chǎn)生用于控制對(duì)象位置、速度和方向的信號(hào)。HAL7xy包含溫度補(bǔ)償和主動(dòng)偏置補(bǔ)償。這些特性在全溫度和全電壓范圍內(nèi)提供了優(yōu)越的穩(wěn)定性，以及適應(yīng)機(jī)械應(yīng)力的開關(guān)點(diǎn)。HAL 7xy產(chǎn)品系為工業(yè)和汽車應(yīng)用設(shè)計(jì)，工作電壓范圍從3.8伏到24伏，環(huán)境溫度范圍從–40 °C 到170 °C。產(chǎn)品有 SMD OT89B封裝。

特性 Features

·Operates from –40 °C up to 170 °C junction temperature
·Operates from 3.8 V to 24 V supply voltage
·Generation of a direction signal (HAL 730 only)
·Operates with static magnetic fields and dynamic magnetic fields up to 10 kHz
·Overvoltage protection at all pins
·Reverse-voltage protection at VDD pin
·Magnetic characteristics are robust against mechanical stress effects
·Short-circuit protected open-drain outputs by thermal shut down
·Constant switching points over a wide supply voltage and temperature range
·The decrease of magnetic flux density caused by rising temperature in the sen- sor system is compensated by a built-in negative temperature coefficient of the magnetic characteristics
