Description說明
The A3282 Hall-effect sensor IC is a temperature stable, stress-resistant latch.在A3282霍爾效應(yīng)傳感器IC是溫度穩(wěn)定，抗逆閂鎖。 Superior high-temperature performance is made possible through an Allegro? patented dynamic offset cancellation that utilizes chopper-stabilization. This method reduces the offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress.優(yōu)異的高低溫性能是透過一快板?專利的動態(tài)偏移取消，利用斬波穩(wěn)定。這種方法降低了應(yīng)力引起的失調(diào)電壓通常由器件超模壓，溫度依存性及熱。 The A3282 complements the current Allegro family of chopper-stabilized latching devices.補(bǔ)充了穩(wěn)定的A3282目前的快板閉鎖裝置系列菜刀。
The A3282 includes the following on a single silicon chip: voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short circuit protected open-drain output.該芯片包括以下A3282在單硅片上：穩(wěn)壓器，霍爾電壓發(fā)生器，小信號放大器，穩(wěn)定斬波，施密特觸發(fā)器和短路保護(hù)開漏輸出。 Advanced BiCMOS wafer fabrication processing is used to take advantage of low-voltage requirements, component matching, very low input-offset errors, and small component geometries.先進(jìn)的BiCMOS晶片加工工藝用于拍攝，利用低電壓要求，元件匹配極低的輸入偏移錯誤和小型元件幾何尺寸。
This device requires the presence of both south and north polarity magnetic fields for operation.本設(shè)備需要的運(yùn)作存在南北兩個領(lǐng)域的極性磁性。 In the presence of a south polarity field of sufficient strength, the device output latches on, and only switches off when a north polarity field of sufficient strength is present.在外地的力量存在足夠的一南極性，器件的輸出閂鎖狀態(tài)，只有當(dāng)一個關(guān)閉北極磁場強(qiáng)度足夠存在。
The A3282 is rated for operation between the ambient temperatures –40°C and 85°C for the E temperature range, and –40°C to 150°C for the L temperature range.在A3282的額定工作環(huán)境溫度之間的-40 ° C和85 ° C的溫度范圍內(nèi)的電子，和-40 ° C至150 ° C的溫度范圍內(nèi)的L。 The two package styles available provide magnetically optimized solutions for most applications. Package LH is an SOT23W, a miniature low-profile surface-mount package, while package UA is a three-lead ultramini SIP for through-hole mounting.這兩個封裝類型的應(yīng)用提供磁性優(yōu)化的解決方案最多。封裝LH是的SOT23W，微型低厚度表面安裝封裝，而封裝UA是通過孔安裝的三引腳超小型SIP。 Each package is available in a lead (Pb) free version, with 100% matte tin plated leadframes.每個包的版本是采用無鉛（Pb）的自由，與100％霧錫電鍍引線框架。
