汽车级电流隔离式电流传感器 IC，采用小尺寸薄型封装，具有共模场抑制和过流检测

ACS71240 系列单片霍尔效应电流传感器 IC 符合汽车 AEC-Q100 标准，是广受欢迎的 Allegro ACS711 系列电流传感器 IC 的下一代改进产品。这些改进包括对杂散磁场（由相邻电机或载流导线产生）的输出信号抗扰度、改善的输出信号精度（典型值 <+/-1.5%）和输出信号对噪声电源电压轨的抗扰度。该器件还具有专用的快速过流故障输出，其典型响应时间为 1.5 us。这种快速故障输出提供了检测短路事件的简单方法，可防止逆变器、电机或其他开关电力电子应用中的 MOSFET 或 IGBT 损坏。\n\n ACS71240 提供两种非常小封装选项，每种封装都提供不同级别的电 • 获得 AEC-Q100 认证\n • 差分霍尔传感抑制共模杂散磁场\n • 过流故障，工厂可编程跳闸范围为满量程电流的 50% 至 200%\n • 非比例输出可提供对嘈杂电源的抗扰度\n • 电隔离：• QFN 封装：120VDC 工作电压\n • SOIC8 封装UL 认证为 2400VRMS，工作电压为 420VDC 或 297VRMS\n\n • 更低功率损耗：• 0.6 mΩ 内部导体电阻（QFN 封装）\n • 1.2 mΩ 内部导体电阻（SOIC8 封装）\n\n • 集成屏蔽实际上消除了从电流导体至晶片的电容耦合，显著抑制了高 dv/dt 瞬变导致的输出噪声;
