　　Description: The MS32 is a magnetic field sensor which is built in the form of a Wheatstone bridge. Each of its four resistors is made from Permalloy, a material that shows the anisotropic magneto resistance effect. An uni-directional magnetic field in the surface parallel to the chip (x-y plane) along the y-axis will deliver a field dependent output signal. A magnetic switching point, which is almost independent on temperature is typically set to Hs=1.85 kA/m. In addition, the characteristic curve is linear over a wide magnetic field range. Thus, the new MS32 simplifies the adaption of the sensor to different mechanical and magnetical environ-ments. The sensor die is packaged in a modern TDFN package.

　　典型应用: 工业/消费品/汽车领域非接触位置检测，小冲程气缸，笔记本和手机翻盖位置，门/窗开关

　　行业: 消费电子和家用电器

　　产品描述: MS32磁阻传感器的内部结构为一个惠斯通电桥，由四个具有各向异性磁阻效应的坡莫合金电阻组成。沿着Y轴平行于芯片表面（X-Y平面）的单向磁场将产生一个输出信号。磁场开关点一般设置为Hs=1.85kA/m（几乎不受温度影响）。此外，在较大磁场范围内的特性曲线是线性的。因此，MS32对不同机械环境和磁场环境的适应性非常强。传感器采用了流行的TDFN封装。

　　特点:

　　传感器基于固态磁阻效应
　　单极信号输出
　　线性磁场响应
　　高灵敏度，低磁滞
　　温度补偿开关点
　　高桥路阻抗，低功耗
　　供电电压<30V
　　小型TDFN封装
