ACS709屬于傳感器變送器的電流傳感器。由Allegro MicroSystems制造生產(chǎn)的ACS709電流傳感器電流傳感器用于檢測并響應(yīng)電線或電路中的電流變化。傳感器類型包括電流開關(guān)式、磁通門式、霍爾效應(yīng)式、電流指示器、電流傳感器、磁調(diào)制器、磁阻式和變壓器式（帶調(diào)節(jié)功能），電流檢測范圍可編程設(shè)置在 5mA 至 2500A 之間，可用于測量交流或直流電流。

Description

The Allegro? ACS709 current sensor IC provides economical and precise means for current sensing applications in industrial, automotive, commercial, and communications systems. The device is offered in a small footprint surface mount package that allows easy implementation in customer applications.

Features and Benefits

? Industry-leading noise performance with 120 kHz bandwidth through proprietary amplifier and filter design techniques

? Integrated shield greatly reduces capacitive coupling from current conductor to die due to high dV/dt, and prevents offset drift in high-side applications

? Small footprint surface mount QSOP24 package

? 2100 VRMS isolation voltage between primary current path and sensor IC electronics

? 1.1 mΩ primary conductor resistance for low power loss

? User-settable Overcurrent Fault level

? Overcurrent Fault signal typically responds to an overcurrent condition in < 2 μs

? Filter pin capacitor sets analog signal bandwidth

? ±2 typical output error

? 3 to 5.5 V, single supply operation

? Factory trimmed sensitivity, quiescent output voltage, and associated temperature coefficients

? Chopper stabilization results in extremely stable quiescent output voltage

? Ratiometric output from supply voltage
