HAR3726DJ-A数据手册TDK-Micronas中文资料规格书

描述 Description

HAL 37xy是使用Micronas专利 3D HAL技术的第二代传感器产品，提供更加完善的角度测量性能。和第一代相比，角度测量误差减少30%。
由于技术的进步，产品可以在低至 ±20 mT的磁场工作。HAL 3715和HAL 372x提供线性、比率模拟输出信号，还有拉起或拉下电阻集成断线探测。HAL 37xy有脉宽调制和SENT SAEJ2716 rev. 2010数码输出格式。输出格式是客户可编程的。产品能测量BX, BY和BZ方向的磁场分量。这让它适用于很多潜在的位置探测应用，比如远距离，者过轴角度测量。芯片信号处理计算两个方向的磁场并且将数值转换为输出信号。因为测量方法，传感器在特定温度范围内展现出优秀的飘移表现，这带来了一个角度或线性测量的全新精确水平。产品具有逐步任意可编程线性特性。可以通过在非易失性内存中进行编程来调整磁电路的主要特性。产品包括先进的诊断功能加强失效安全检查。产品设计适用于汽车和工业应用，温度范围从−40 °C 到 170 °C，包装有小尺寸四引角含铅二极管TO92UP封装，也有 SOIC8封装。
