ACS759KCB-150B-PFF-T Allegro 霍爾電流傳感器的應(yīng)用
為了自動檢測和顯示電流，并在過流、過壓等危害情況發(fā)生時具有自動保護功能和更高 級的智能控制，具有傳感檢測、傳感采樣、傳感保護的電源技術(shù)漸成趨勢，檢測電流或電壓的傳感器便應(yīng)運而生，并受到廣大電源設(shè)計者的青睞。
電流傳感器是一種檢測裝置，能感受到被測電流的信息，并能將檢測感受到的信息，按一定規(guī)律變換成為符合一定標準需要的電信號或其他所需形式的信息輸出，以滿足信息的傳輸、處理、存儲、顯示、記錄和控制等要求。
電流傳感器可以在家用電器、智能電網(wǎng)、電動車、風(fēng)力發(fā)電等等，在我們生活中都用到很多這類磁傳感器，比如說電腦硬盤、指南針，家用電器等等。
電流傳感器依據(jù)測量原理不同，主要可分為：分流器、電磁式電流互感器、電子式電流互感器等。
電子式電流互感器包括霍爾電流傳感器、羅柯夫斯基電流傳感器及專用于變頻電量測量的AnyWay變頻功率傳感器（可用于電壓、電流和功率測量）等。
與電磁式電流傳感器相比較，電子式電流互感器沒有鐵磁飽和，傳輸頻帶寬，二次負荷容量小、尺寸小、重量輕、是今后電流傳感器的發(fā)展方向。

1.電機。 在無刷電動機中,用磁傳感器來作轉(zhuǎn)子磁極位置傳感和定子電樞電流換向器,磁傳感器中,霍爾器件,威根德器件,磁阻器件等都可以使用,但主要還是以霍爾傳感器為主,另外磁傳感器還可以對電機進行過載保護及轉(zhuǎn)矩檢測...
2.電力電子技術(shù)。 電力電子表技術(shù)是電力技術(shù)和電子技術(shù)的結(jié)合,可實現(xiàn)交直流電流的相互變換,并可在所需的范圍內(nèi)實現(xiàn)電流,電壓和頻率的...
The Allegro?ACS759 family of current sensor ICs provides economical and precise solutions for AC or DC current sensing. Typical applications include motor control, load detection and management, power supply and DC-to-DC converter control, inverter control, and overcurrent fault detection.The device consists of a precision, low-offset linear Hall circuit with a copper conduction path located near the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional output voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy at the factory.High-level immunity to current conductor dV/dt and stray electric fields, offered by Allegroproprietary integrated shield technology, for low output voltage ripple and low offset drift in high-side, high-voltage applications.The output of the device has a positive slope (>VCC/ 2) when an increasing current flows through the primary copper conduction path (from terminal 4 to terminal 5), which is the path used for current sampling. The internal resistance of this conductive path is 100 μ? typical, providing low power loss. The thickness of the copper conductor allows survival of the device at high overcurrent conditions. The terminals of the conductive path are electrically isolated from the signal leads
