Other Parts Discussed in Thread: TMAG5170
Dear Sir, Madam,
I have an other question about the temperature drift of the TMAG5170.
How does the temperature compensation coefficient work ?
For instance, I take a sensor set to the +/-50mT range and I detect 45mT maximum at 25°C. At -40°C, the magnetic field measured could be worth between 43,065mT (45 - 4.3%*45 = 45 - 1.935) and 46,935mT (45 + 4.3%*45 = 45 + 1.935). I saw on the datasheet the temperature compensation for NdBFe magnet is 0.12%/°C.
Is the temperature compensation worth 0.12%*(25 - (-40)) = 7.8% at -40°C ?
How do I have to apply this temperature compensation to the magnetic field values ? Can you provide me a formula in order to explain that please ?
