9.1.2 Temperature Compensation for Magnets

The magnetic field of magnets based on Neodymium or the Ferrite magnets have a high temperature coefficient. The residual induction (Br) of a magnet typically reduces by 0.12%/°C for NdFeB, and 0.20%/°C for ferrite material. The TMAG5253 features sensitivity temperature compensation that is designed to directly compensate the average drift of magnets. When the operating temperature range of a system is reduced, temperature drift errors are also reduced.

For device options BA1 to BA4 and UA5, the sensitivity at TA = 125°C is typically 12% higher than at TA = 25°C. These device options are typically used when Neodymium magnets are used along with the TMAG5253. These options are typically used when measuring ambient currents or when the magnetic field does not vary with temperature.
