ACS71240:汽车等级,电流隔离电流传感器IC,具有共模场抑制和小型占地面积低型封装的过流检测

描述

ACS71240汽车AEC-Q100系列合格,单片霍尔效应电流传感器IC提供了流行的Allegro ACS711前身电流传感器IC系列的下一代改进。这些改进包括对杂散磁场的输出信号免疫(由相邻的电动机或电流承载线产生),提高输出信号精度(典型的典型值<+/- 1.5%)和输出信号免疫力到噪声电源电压轨。该器件还具有专用的快速过电流故障输出,具有1.5件的典型响应时间。此快速故障输出提供了一种检测短路事件的简单方法,可防止MOSFET或IGBT损坏逆变器,电机或其他开关电源电子产品应用。雷竞技最新网址

ACS71240以两种非常小的形状包装选项提供,每个包装选项提供不同的电流隔离级别。可润湿的侧翼QFN封装的微小3mm x 3mm,可在电压轨上使用,高达120VDC,并在零PPM汽车应用中实现焊接接头检测。雷竞技最新网址标准占地面积SOIC8包装为UL认证到2400VRMS隔离,提供420VDC或297VRMS的工作电压。

The ACS71240 family is designed to replace shunt resistors, operational amplifiers, current transformers and voltage isolators in applications that require small form factor, monolithic sensor solutions. These fully integrated solutions reduce the overall cost of current sensing by eliminating discrete components that demand printed circuit board area. The sensors are offered for use on 5V or 3.3V power supplies.
