Allegro ACS710 120kHz带宽Hall传感方案

Allegro公司的ACS710是120kHz带宽霍尔电流传感器,包括高度线性的霍尔传感器和靠近硅芯片表面的铜导电通路(基本电阻1毫欧姆), 适合于火线应用的高绝缘电压,单电源3-5.5V工作,主要应用在马达控制,负载管理和过流检测,电源转换和电池监测.本文介绍了ACS710的主要特性,功能方框图和典型应用电路.

The Allegro® ACS710 current sensor provides economical and precise means for current sensing applications in industrial, commercial, and communications systems. The device is offered in a small footprint surface mount package that allows easy implementation in customer applications.

The ACS710 consists of a precision linear Hall sensor integrated circuit with a copper conduction path located near the surface of the silicon die. Applied current flows through the copper conduction path, and the analog output voltage from the Hall sensor linearly tracks the magnetic field generated by the applied current. The accuracy of the ACS710 is maximized with this patented packaging configuration because the Hall element is situated in extremely close proximity to the current to be measured.
