　　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.

　　Features:

　　Sensor based on solid state magnetoresistance effect
　　Unipolar signal output
　　Linear field response
　　High sensitivity, low hysteresis
　　Temperature compensated switching point
　　Low power consumption due to high bridge resistance
　　Supply voltage up to 30 V allowed
　　Small TDFN package

　　典型應用: 工業/消費品/汽車領域非接觸位置檢測，小沖程氣缸，筆記本和手機翻蓋位置，門/窗開關

　　行業: 消費電子和家用電器

　　產品描述: MS32磁阻傳感器的內部結構為一個惠斯通電橋，由四個具有各向異性磁阻效應的坡莫合金電阻組成。沿著Y軸平行于芯片表面（X-Y平面）的單向磁場將產生一個輸出信號。磁場開關點一般設置為Hs=1.85kA/m（幾乎不受溫度影響）。此外，在較大磁場范圍內的特性曲線是線性的。因此，MS32對不同機械環境和磁場環境的適應性非常強。傳感器采用了流行的TDFN封裝。

　　特點:

　　傳感器基于固態磁阻效應
　　單極信號輸出
　　線性磁場響應
　　高靈敏度，低磁滯
　　溫度補償開關點
　　高橋路阻抗，低功耗
　　供電電壓<30V
　　小型TDFN封裝
