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 unidirectional 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
environments. The sensor die is packaged in a TDFN package.
Features:
