50 to 200 A Integrated Current Sensor ICs

The Allegro CA and CB package current sensor ICs are fully integrated current sensor solutions. They contain the primary conductor, concentrating ferromagnetic core and the analog output Hall-effect linear in a single IC package. The conductor resistance is a typical of 100 µΩ for ultra low power loss when sensing current up to 200 A. These sensors are automotive grade devices that can take the heat and deliver highly accurate open loop current sensing in the most harsh applications environments.

The Allegro medium current devices are much smaller than bulky current transformers and have the added advantage of sensing both AC and DC currents. The package design also provides galvanic isolation to 3000 V_RMS and can be used in many line side applications.

llegro MicroSystems, LLC开发了一系列全面集成的霍尔效应电流传感器和霍尔效应线性集成电路，这些电路提供与应用AC或DC电流相称的高精确度、低噪声输出电压信号。这些IC在很多应用中大量生产，包括汽车HEV逆变器和电动助力转向(EPS)系统，在工业和消费逆变器和电动机控制应用中也大量生产。

Allegro电流传感器IC也用于很多电源监测应用，如计算机刀片式服务器和服务器电源。Allegro的专有全面集成霍尔效应电流传感器IC运用先进的IC和封装技术来感应5 A到200 A的电流。 这些集成解决方案为高效解决方案提供初级导体(≤1mΩ)的电流隔离（最大4.8 kV）和极低电阻，提供多种表面封装和通孔封装可选。 对于超过200 A的传感，可使用Allegro线性电流传感器。

Allegro电流传感器IC 允许设计工程师将基于霍尔效应的电流传感器IC用于要求提高能源效率或新运行特点的新应用。
