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

產(chǎn)品描述: MS32磁阻傳感器的內(nèi)部結(jié)構(gòu)為一個惠斯通電橋，由四個具有各向異性磁阻效應(yīng)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(chǎn)生一個輸出信號。磁場開關(guān)點一般設(shè)置為Hs=1.85kA/m（幾乎不受溫度影響）。此外，在較大磁場范圍內(nèi)的特性曲線是線性的。因此，MS32對不同機械環(huán)境和磁場環(huán)境的適應(yīng)性非常強。傳感器采用了流行的TDFN封裝。
