Product Details

Top Features

  • 获得 AEC-Q100 认证
  • 差分霍尔传感抑制共模杂散磁场
  • 过流故障，工厂可编程跳闸范围为满量程电流的 50% 至 200%
  • 非比例输出可提供对嘈杂电源的抗扰度
  • 电隔离：
    • QFN 封装：120VDC 工作电压
    • SOIC8 封装UL 认证为 2400VRMS，工作电压为 420VDC 或 297VRMS
  • 更低功率损耗：
    • 0.6 mΩ 内部导体电阻（QFN 封装）
    • 1.2 mΩ 内部导体电阻（SOIC8 封装）
  • 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
  • 与交直流电流成正比的输出电压
  • 高带宽 120 KHz 模拟输出缩短了控制应用中的响应时间
  • 工厂校准灵敏度和静态输出电压用于改进精确度
  • 3.3 和 5 V，单电源操作
  • 小尺寸纤薄 QFN 和 SOIC8 封装适合空间有限的应用
